segmentation fault when running with --test-socket option #12

Closed bluesabre closed 4 years ago

bluesabre commented 4 years ago

to reproduce run lightdm-gtk-greeter --test-socket or lightdm-gtk-greeter-pkexec test socket and you will get a segmentation fault asking you to authenticate the program seems to start but then has a segmentation fualt.

ightdm-gtk-greeter-settings:: Installed: 1.2.0-0ubuntu1 Candidate: 1.2.0-0ubuntu1 Version table: *** 1.2.0-0ubuntu1 0 500 http://us.archive.ubuntu.com/ubuntu/ wily/universe i386 Packages 100 /var/lib/dpkg/status Description: Ubuntu Wily Werewolf (development branch) Release: 15.10

I expected this to not segmentation fualt and give a permission denid when running as regualr user or not perofmr a segmentaion fault when run as pkexec.

I can confirm this locally: "lightdm-gtk-greeter-settings --test-socket" runs as non-root and shows a "Test embedded mode window", but the elements are quite flickery and the program segfaults on quit. That said, I'm not sure what the purpose of this option is, and whether it's supposed to be used by a regular user.
