Introduction

QGIS is a powerful and widely-used Geographic Information System (GIS) software that provides a robust platform for geospatial analysis and visualization. However, like any complex software, QGIS can sometimes experience issues that can lead to crashes and errors. In this article, we will explore a specific issue where QGIS crashes on startup due to the qris_deploy plugin.

Symptoms

The symptoms of this issue are as follows:

QGIS crashes immediately after opening an existing project.
When opening the QGIS app instead of an existing project, a different error message is displayed, but the qris_deploy plugin is still disabled due to a previous crash.
The crash report indicates that the qris_deploy plugin is causing the issue.

Crash Report Analysis

The crash report provided in the original issue description is a crucial piece of information that helps us understand the root cause of the problem. Let's break down the key components of the crash report:

Python Stack Trace: The Python stack trace indicates that the issue is occurring in the qrave_integration.py file, which is part of the qris_deploy plugin. Specifically, the error occurs when the self.BaseMaps.load() method is called.
Stack Trace: The stack trace provides a detailed view of the function calls that led to the crash. In this case, the issue is caused by a recursive function call that eventually leads to a ModuleNotFoundError.
QGIS Info: The QGIS info section provides information about the QGIS version, code revision, and the Qt and GDAL versions used.
System Info: The system info section provides information about the CPU type, kernel type, and kernel version.

Root Cause Analysis

Based on the crash report analysis, the root cause of the issue appears to be a recursive function call in the qrave_integration.py file that leads to a ModuleNotFoundError. This error occurs because the rsxml module is not installed or is not available in the Python path.

Solution

To resolve this issue, we need to ensure that the rsxml module is installed and available in the Python path. Here are the steps to follow:

Install the rsxml module: You can install the rsxml module using pip by running the following command in your terminal or command prompt:

pip install rsxml


2.  **Verify the Python path**: Ensure that the `rsxml` module is available in the Python path by checking the `PYTHONPATH` environment variable. You can do this by running the following command in your terminal or command prompt:

    ```bash
echo $PYTHONPATH

This will display the current Python path. If the `rsxml` module is not available in the Python path, you can add the path to the `rsxml` module to the `PYTHONPATH` environment variable.

Disable the qris_deploy plugin: To prevent the qris_deploy plugin from crashing QGIS, you can disable it by removing the qris_deploy plugin from the QGIS plugin directory. You can do this by deleting the qris_deploy directory from the C:\Users\chloe\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins directory.

Conclusion

In conclusion, the qris_deploy plugin is causing QGIS to crash on startup due to a recursive function call that leads to a ModuleNotFoundError. To resolve this issue, we need to ensure that the rsxml module is installed and available in the Python path. By following the steps outlined in this article, you should be able to resolve this issue and prevent QGIS from crashing on startup.

Additional Tips

Regularly update QGIS and plugins: Regularly updating QGIS and plugins can help prevent issues like this from occurring.
Use a version control system: Using a version control system like Git can help you track changes to your QGIS projects and plugins, making it easier to identify and resolve issues.
Test plugins thoroughly: Thoroughly testing plugins before using them in production can help identify issues like this before they cause problems.

Q: How do I install the `rsxml` module?

A: You can install the rsxml module using pip by running the following command in your terminal or command prompt:

pip install rsxml

Q: How do I verify the Python path?

A: You can verify the Python path by checking the PYTHONPATH environment variable. You can do this by running the following command in your terminal or command prompt:

echo $PYTHONPATH

This will display the current Python path. If the rsxml module is not available in the Python path, you can add the path to the rsxml module to the PYTHONPATH environment variable.

Q: How do I disable the qris_deploy plugin?

A: To prevent the qris_deploy plugin from crashing QGIS, you can disable it by removing the qris_deploy plugin from the QGIS plugin directory. You can do this by deleting the qris_deploy directory from the C:\Users\chloe\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins directory.
