Thanks for the bug report.

qt dereferences a 0x0 pointer in notifyInternal:

#0  QCoreApplication::notifyInternal (this=0x3572320, receiver=0x0, event=0x7f394cffe4e0) at kernel/qcoreapplication.cpp:902

Reassigning to qt

Comment 6 Kevin Kofler 2012-07-19 22:53:47 UTC
I don't think it's a Qt bug, it's more likely to be an application bug, or possibly a bug in PyQt4. It's invalid to destroy a QObject which has pending signals. The fix is usually to destroy the object with deleteLater rather than delete.

Comment 7 Fedora End Of Life 2013-01-16 20:30:42 UTC
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '16'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 16 is end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" and open it against that version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 8 Fedora End Of Life 2013-02-13 23:54:56 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no longer maintained, which means that it will not receive any further 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.
