Package: libcogl9
Version: 1.10.2-6
Severity: normal
Tags: upstream
On my mostly wheezy-ish system, gnome-control-center segfaults with the
following back trace. I'm not quite sure what's wrong, but reading the code
in cogl-pipeline-fragend-arbfp.c, it looks strange to pass on a pointer
to gl_program, when that itself is NULL. Especially in combination with the
params=0x2d argument for __indirect_glProgramParameters4fvNV().
Note that I don't have an ordinary gnome-session running, nor is the
gnome-settings-daemon up - if that matters.
Note that 1.10.2-6exp1 fails in the very same way. I didn't test 1.12, as I
don't expect that to hit wheezy, anymore.
Program received signal SIGSEGV, Segmentation fault.
