session: fix corruption of GDM_LANG environment variable (4.45 KB, patch)

Description Ray Strode [halfline] 2015-08-24 16:51:39 UTC 
commit cab736cfb32aa25677287ff261ae1cb11f036e89 introduced a
bug that leads to GDM_LANG getting set to gibberish.  This
causes spew to the log and, in some cases, prevents successful
login.

This commit addresses the problem by duplicating a string that
is, otherwise, freed before its second use.

Not sure if it is relative, but Chrome (not Chromium) and Telegram desktop app, on cases logs me off on GDM session.

Fedora Rawhide. 
gnome-shell-3.17.90-1.fc24.x86_64
gdm-3.17.90-1.fc24.x86_64

no probably not related. that's more likely the X server crashing?

I cannot see an Xserver error in Journalctl.
How can I debug this?
Comment 6 Ray Strode [halfline] 2015-08-28 19:55:50 UTC 
coredumpctl should give you a list of recent crashes

you could also try enabling debug in /etc/gdm/custom.conf to get a more complete log in the journal.

coredumpctl doesn't show anything.
I enabled debug on /etc/gdm/custom.conf.
If I catch the error I will open a new bug report. 

Thanks!

That proved to be a Fedora bug, not GNOME one. 
It happens on KDE too, with LightDM.
