Description Ewgenij Starostin 2007-10-14 20:19:43 UTC
If xorg-xserver has been built with the hal USE flag and is started while the dbus service is not running, it crashes when shut down by exiting the wm or pressing ctrl-alt-backspace. The console is unusable but the rest of the system is not affected (e. g. remote login works).

When dbus is running, X shuts down properly. From the backtrace, I suspect that the problem is in teardown() in xorg-server-1.4/config/dbus-core.c, but I have not been able to test that in gdb.

Reproducible: Always

Steps to Reproduce:
1. Build x11-base/xorg-xserver-1.4.0-r2 with hal.
2. Stop dbus.
3. Run X.
4. Stop X.
Actual Results:  
X crashes on a segmentation fault.

Expected Results:  
X should shut down properly (or fail to start, if that is not possible).

Backtrace from Xorg.0.log:
0: X [0x80e9c66]
1: X(xf86SigHandler+0xa3) [0x80e9c12]
2: [0xb7fbd420]
