*** This bug has been marked as a duplicate of bug 727778 ***
This is probably more complicated. Rather reopening.
There are similar backtraces in bug 663804, bug 727778 (and perhaps bug 703155). Less similar (but perhaps in the same function) are bug 714746 and bug 710564.
Fatal server error: [261172.189] Caught signal 3 (Quit). Server aborting
I can't reproduce this with F16 as of today. Dan, are you still seeing this?
Looks good.
