User Feedback

I was right-clicking on the recent projects screen to remove a project from the list. I suspect the project had been moved in the file system.

History

#1 Updated by Richard Duivenvoorde almost 3 years ago

Is this reproducible by you on your machine?

Here I tried to test this by creating 3 projects in /tmp, then remove one of the project files of it and then reopening QGIS.
While the removed project is grayed out, I can happily use the right click menu there and remove it from the list...

Mmm, I had a crash at a certain moment, just after removing an (excisting) project from the projectlist:

Fatal: ASSERT failure in QList<T>::at: "index out of range", file /usr/include/x86_64-linux-gnu/qt5/QtCore/qlist.h, line 541
QGIS died on signal -1[New LWP 16353]
[New LWP 16354]
[New LWP 16355]

Will try with gdb

Just after removing (a last) item from the last projects list (via right click menu):
