Description of problem: When starting or exiting many PyQt applications I seem to see a segmentation fault. This seems to have started after the recent kde 4.4.2 update. Version-Release number of selected component (if applicable): PyQt4-4.7.2-2.fc12.x86_64 How reproducible: Every time Steps to Reproduce: 1. Install PyQt4-devel package 2. Run "python /usr/share/doc/PyQt4-devel-4.7.2/examples/dialogs/standarddialogs.py" 3. Exit program Actual results: Segmentation fault when exiting Expected results: No segmentation fault Some demos don't appear to work at all: xpc1:~:$ python /usr/share/doc/PyQt4-devel-4.7.2/examples/demos/qtdemo/qtdemo.py Segmentation fault (core dumped) Additional info:
Not reproducible by me $ rpm -q sip PyQt4 qt sip-4.10.1-2.fc12.x86_64 PyQt4-4.7.2-2.fc12.x86_64 qt-4.6.2-14.fc12.x86_64 Could you get a backtrace perhaps?
Created attachment 407900 [details] backtrace
Created attachment 407901 [details] another backtrace
The problem goes away when reverting to PyQt4-4.7-1.fc12.x86_64
Mind testing with these newer builds? sip-4.10.2-1.fc12: http://koji.fedoraproject.org/koji/buildinfo?buildID=168044 PyQt4-4.7.3-1.fc12: http://koji.fedoraproject.org/koji/buildinfo?buildID=168053
Thanks - that seems to have got rid of the segmentation faults. I still get the bug where my own program with a QTableView shows blank entries (showing a model which shows floating point numbers). I expect this is due to a bug in my own code or in the new PyQt. Should I open a new bug for this?
My table view bug looks like it's a subtle problem in the new PyQt where values in numpy arrays used to cast okay to QVariants, but now they do not. I've worked around it be casting to a float in between. I've asked upstream PyQt whether this is a bug or my problem.
