[IPython-user] crash of qt application only happens when ipython -qthread arg is used

[Glen W. Mabey]

Hello,

I'm using ipython 0.8.1 but have seen this problem with previous
versions of ipython.

When I %run a script from ipython when the -qthread option has been
used, there is a segfault at about the time when the window should
appear in the window manager.

Loading the core into gdb reveals:

Core was generated by `/usr/local/bin/python2.5 /usr/local/bin/ipython -qthread'.
Program terminated with signal 11, Segmentation fault.
#0  0x419368ae in ?? () from /usr/lib/libz.so.1
(gdb) bt
#0  0x419368ae in ?? () from /usr/lib/libz.so.1
#1  0x00000000 in ?? ()


Versions include python 2.5.1, pyqt 3.17.2, qt 3.3.8 but there are a
whole buncha other modules in use, including numpy (svn) and scipy (svn),
so I'm not quite sure where to start.

Any suggestions?  Note that there is no segfault when running the same
commands but without the -qthread option.

Thanks,
Glen
