Thank you for reporting this bug. How reproducible is this problem? If you run the program from a terminal, is an error message printed? What is the output of running the following command? rpm -q qt Looking at the backtrace, it looks like the problem occurred in thread #1 in x11EventSourceCheck Reassigning component from "python" to "qt"; hopefully the qt maintainer will be able to figure this out further or reassign as necessary.
That code appears to be mixing wxGTK with PyQt4, a strange combination. I've seen this same crash location before in a mixed GTK+/Qt scenario, not sure whether it was gtk-qt-engine (no longer supported) or QGtkStyle. In any case, it seems Qt's glib event loop integration is getting confused by some events GTK+ is producing. It appears to be a Qt bug.
(It was in a report filed by somebody else, but I couldn't find the bug ID anymore. That said, searching for x11EventSourceCheck on the web finds a lot of bugs.)

You need to install IPython from the trunk: bzr branch lp:~fdo.perez/ipython/trunk-dev do python setup.py install and run "ipython-wx" Fernando offered a solution at https://bugs.launchpad.net/ipython/+bug/509330 > > What is the output of running the following command? > rpm -q qt > rpm -q qt qt-4.5.3-9.fc12.i686
If we're going to try to get nokia to look at this, we'll likely need a minimal test-case to demonstrate the bug.
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '12'. 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 12'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 12 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 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.
