Created attachment 104321 [details] drkonqi report Scenario: Open an existing Kdevelop session, that has one Makefile project loaded. Click on expand project folder in the project tool view. Expected results: Folder to expand and show it's contents. Actual result: KDevelop crashes. I had the same behaviour with KDevelop 5.0.3, but I have 5.0.1 currently installed and I'm able to reproduce it. If I delete the session and cache directories, and reload the project, manually, projects loads normally, and expanding causes no crashes.
I still experience this in KDevelop 5.0.3 from the AppImage. But it only happens sometimes. I couldn't isolate the exact time when this happens, so far.

I've never seen this, can anyone get this to crash with more debug symbols to show us what line is triggering this? without that information, we can only fish in the dark
This seems to manifest after some time of working on my work projects. These projects have a very (unnecessarily) complicated Makefile based build system, and that is how they are loaded in KDevelop. I wouldn't put this issue past the fact that the structure of the build system just drives KDevelop nuts. I don't know how effectively I can reproduce this bug, without providing the entire Build system configuration, which I cannot do. Does the stack trace not help?
Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days, the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please set the bug status as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone!
I can no longer reproduce this, as I no longer have access to the project that caused this. Also, the project migrated to CMake.
