Bug ID: 892359
Summary: transmission-gt[1948]: segfault at 1 ip
000000322fa14443 sp 00007fff45fb16a8 error 4 in
libpango-1.0.so.0.3200.3[322fa00000+49000]
Product: Fedora
Version: 18
Component: pango
Severity: unspecified
Priority: unspecified
Reporter: kparal(a)redhat.com
Description of problem:
Recently the transmission application started to either crash or display
graphical glitches. If I try to open any dialog (application preferences,
torrent details), one of these three things happen at random:
1) dialog is displayed fine
2) application crashes
3) I see a large black rectangle of huge proportions (e.g. 10000x10000 px). If
I shrink the black rectangle to a reasonable size, it redraws into a working
dialog. It is black in those huge proportions probably because my Intel video
card can't render such large windows.
When it crashes, I see this in dmesg:
transmission-gt[1948]: segfault at 1 ip 000000322fa14443 sp
00007fff45fb16a8 error 4 in libpango-1.0.so.0.3200.3[322fa00000+49000]
Abrt doesn't kick in, so I enabled coredump creation manually and extracted the
backtrace. It seems to be a crash in pango:

I have the core file available if it helps.
I tried to downgrade transmission, xorg-x11-server-Xorg, xorg-x11-drv-intel,
but nothing helps. I can't downgrade pango, it's the only version available in
F18.
But I believe I have used transmission quite a few times some weeks ago and I
never saw this problem.
Version-Release number of selected component (if applicable):
pango-1.32.3-1.fc18.x86_64
transmission-gtk-2.75-1.fc18.x86_64
xorg-x11-drv-intel-2.20.17-1.fc18.x86_64
xorg-x11-server-Xorg-1.13.1-1.fc18.x86_64
How reproducible:
easily
Steps to Reproduce:
1. start transmission
2. if you have some torrent, select it and repeat: open its properties window,
close it, open it again, close it, ...
3. alternatively you can do the same with transmission preferences window
4. after a few attempts you should see either a big black rectangle covering
the whole screen or program crash
