Description of problem: A python program written in wxpython segfaults. Version-Release number of selected component (if applicable): wxPython.x86_64 2.8.9.2-2.fc11 How reproducible: Always Steps to Reproduce: 1. save the attached code in a file (TableEditor_demo.py). It is a demo that comes with the Traits package python-Traits. It requires wx backend for traits http://pypi.python.org/pypi/TraitsBackendWX/3.1.0 (this is pure python) 2. Run the demo $ gdb python $ run TableEditor_demo.py 3. Click on any table entry which changes to a text field. 4. Click on close button. 5. Observe the segfault in gdb (As this is very small demo clicking on close button causes segfault. If another panel could be created, the segfault would be caused by clicking on any other panel apart from the one in which the table is located.) Actual results: This is the backtrace: Program received signal SIGSEGV, Segmentation fault. 0x000000370ee80689 in wxGridCellEditor::Show(bool, wxGridCellAttr*) () from /usr/lib64/libwx_gtk2u_adv-2.8.so.0 (gdb) bt #0 0x000000370ee80689 in wxGridCellEditor::Show(bool, wxGridCellAttr*) () from /usr/lib64/libwx_gtk2u_adv-2.8.so.0 #1 0x000000370ee873d6 in wxGrid::HideCellEditControl() () from /usr/lib64/libwx_gtk2u_adv-2.8.so.0 #2 0x000000370ee8c187 in wxGrid::~wxGrid() () from /usr/lib64/libwx_gtk2u_adv-2.8.so.0 #3 0x000000370f8f1813 in wxWindowBase::DestroyChildren() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #4 0x000000370f7fa862 in wxWindow::~wxWindow() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #5 0x000000370f919b87 in wxPanel::~wxPanel() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #6 0x000000370f8f1813 in wxWindowBase::DestroyChildren() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #7 0x000000370f7fa512 in wxWindow::~wxWindow() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #8 0x000000370f8f1813 in wxWindowBase::DestroyChildren() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #9 0x000000370f7fa862 in wxWindow::~wxWindow() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #10 0x000000370f919b87 in wxPanel::~wxPanel() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #11 0x000000370f8f1813 in wxWindowBase::DestroyChildren() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #12 0x000000370f7fa862 in wxWindow::~wxWindow() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #13 0x000000370f843baa in wxFrame::~wxFrame() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #14 0x000000370f870db2 in wxAppBase::DeletePendingObjects() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #15 0x000000370f870e7b in wxAppBase::ProcessIdle() () from /usr/lib64/libwx_gtk2u_core-2.8.so.0 #16 0x000000370f7ced93 in ??

This used to run normally in previous versions of wxpython (in F10) However i dont know wxpython well enough to attach a self contained test case. But i believe a python app on itself should not be able to segfault, so the problem is either with wx or wxpython.

wxPython-2.8.10.1-1.fc12 has been submitted as an update for Fedora 12. http://admin.fedoraproject.org/updates/wxPython-2.8.10.1-1.fc12
wxPython-2.8.10.1-1.fc11 has been submitted as an update for Fedora 11. http://admin.fedoraproject.org/updates/wxPython-2.8.10.1-1.fc11
wxPython-2.8.10.1-1.fc11 has been pushed to the Fedora 11 stable repository. If problems still persist, please make note of it in this bug report.
wxPython-2.8.10.1-1.fc12 has been pushed to the Fedora 12 stable repository. If problems still persist, please make note of it in this bug report.
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. 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 '11'. 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 11'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 11 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 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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.
