[Python-apps-team] Bug#677421: mayavi2: segfaults as soon as a module is loaded

[Francesco Poli (wintermute)]

Package: mayavi2
Version: 4.1.0-1
Severity: grave
Justification: renders package unusable

Hello,
it seems that I am unable to use mayavi2 on an updated Debian testing
box.

I reproduced this bug with any data set I tried to visualize, hence
the package is currently unusable.


Steps to reproduce:

 0) take some data to visualize and start mayavi2; for instance:

    $ zcat /usr/share/doc/mayavi2/examples/mayavi/data/fire_ug.vtu.gz > fire_ug.vtu
    $ zcat /usr/share/doc/mayavi2/examples/mayavi/data/room_vis.wrl.gz > room_vis.wrl
    $ mayavi2 -d room_vis.wrl -d fire_ug.vtu

 1) add a module; for instance: Streamline, or IsoSurface, or something else
    (it does not seem to make any difference)

 2) mayavi2 exits and the only output on the terminal is
    "Segmentation fault"

 3) /var/log/kern.log  says

    python[10336]: segfault at 1d ip 00007f6b433b387d sp 00007fff89aa30c0 error 4 in libwx_baseu-2.8.so.0.8.0[7f6b432c8000+146000]


My guess is that the segfault has something to do with python-wxgtk2.8,
but I don't know whether it's triggered by some incorrect use on the side
of mayavi2 or rather by some misbehavior of the library...


Please help!
I cannot use mayavi2 until this bug is fixed!

Thanks for your time.
