Description Jan "Yenya" Kasprzak 2006-11-27 12:57:48 EST
Description of problem:
I run OpenOffice.org under Xvfb to do some batchmode conversions. When the
last X client disconnects, the Xvfb crashes with SIGSEGV.

Version-Release number of selected component (if applicable):
xorg-x11-server-Xvfb-1.1.1-47.1.fc6.x86_64 (not tested on other archs)

How reproducible:
100%

Steps to Reproduce:
1. Run Xvfb -ac :1 &
2. Run DISPLAY=:1 oowriter & [or any other X client]
3. after few seconds, kill the oowriter
  
Actual results:
after the X client (oowriter) exits, the Xvfb crashes with SIGSEGV

Expected results:
Xvfb should continue

Additional info:
I have found the following mail:
http://lists.freedesktop.org/archives/xorg/2005-April/007657.html
and indeed, adding "-extension Composite" to the Xvfb command line makes the
problem disappear. So the problem is in the Composite extension of the X server.

core dump

Also reproducible with xorg-x11-server-Xvfb-1.1.1-47.4.fc6 (arch i386). As is
written in comment #1 when I disable Composite extension all works fine. I've
attached core dump if this could help with solving the problem
Comment 2 Adam Jackson 2007-04-05 16:24:21 EDT
Still happens in rawhide, for some reason.  I thought I'd fixed this...
Comment 3 Adam Jackson 2007-04-09 18:59:53 EDT
Will be fixed in 1.2.99.905-2.fc7
