abrt 1.0.1 detected a crash.

How to reproduce
-----
X was hanging and I killed it. The timestamp of this crash indicates that it was caused by that.

Metacity probably had to die, but doing it with sig11 seems wrong

backtrace
-----
Core was generated by `metacity'.
Program terminated with signal 11, Segmentation fault.
