We need a GDB backtrace to hack. See here for details :

This open a file dialog through GTK because you use a GTK based desktop. The crash is inside GTK code. Nice...

This problem must be fixed in 5.6.0 where we drop desktop based file dialog to use in this case.

Please test the last pre-release 5.6.0 Linux AppImage bundle which include this fix.
