Description Dominique Leuenberger 2016-06-20 21:40:31 UTC

Detected by openQA: https://openqa.opensuse.org/tests/213533#step/first_boot/4

Sfreenlocker is broken.

The same issue was already seen in staging on x86_64, but that had been fixed by a patch. Apparently it did not solve i586 (which is not built/tested in stagings though)

Comment 1 Luca Beltrame 2016-06-20 22:00:40 UTC

There needs to be a backtrace in order to understand what's going on in the screensaver. Unfortunately, I don't have i586 hardware to test this with.

If someone can test the snapshot, even in a VM, the easiest way would be

/usr/lib/libexec/kscreenlocker_greet --testing

and see if it crashes. If it does, it needs to be run through gdb to get the bt.

Comment 2 Fabian Vogt 2016-06-21 08:48:02 UTC

The crash can be easily reproduced by running the screenlocker with QV4_MM_AGGRESSIVE_GC=1 set. It produces the following backtrace:

This also breaks plasmashell with a similiar backtrace (valgrind):
