Hi Matt,

if this happens again could you try to get us a backtrace with debuginfo?

Comment 2 Fedora End Of Life 2013-02-14 02:10:42 UTC

Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
