Thanks for the quick response. I exported MOZ_DISABLE_PANGO=1
and ran firefox --debugger gdb. It crashes this time too,
but with different stack trace:
Program received signal SIGSEGV, Segmentation fault.

The above crash and trace I can reproduce every time...
Moments before I tried this, I got a crash in different place:
0x00002ab651f957bf in PL_GetEvent (self=0x139ee30) at plevent.c:467
467 plevent.c: No such file or directory.
in plevent.c
[..]
That trace I can't reproduce however.
Anyway, if I unset MOZ_DISABLE_PANGO and run 'firefox --debugger gdb' again,
it still crashes in TT_New_Context (only this time cairo and pango functions
are in the trace).
Regards,
Oskar
