Short description of error
Blender 2.83 (sub 15) crashes right after closing Preferences dialog on Fedora 32.

Exact steps for others to reproduce the error
Download the Blender 2.83 (sub 15) from the buildbot environment, launch it directly or from the Terminal using

/opt/blender/blender --debug

Under the "File"-menu select "Defaults" and then "Load Factory Settings" to begin fresh. Now go to the "Edit"-menu and select "Preferences". It doesn't matter if chanes are made there or not, click "Save Preferences" and close the Preferences-window. Now it will take a few seconds in which the mouse can be moved and such, after which clicking the mouse will not be registered anymore and Blender itself crashes. The Terminal then contains the following lines:

[machinename@macpro ~]$ /opt/blender/blender --debug
