Description Luca Giuzzi 2010-05-12 20:26:08 UTC
Description of problem:
 mayavi2 refuses to start and/or load under python; the system segfaults. 

Version-Release number of selected component (if applicable):
wxPython 2.8.10.1-3.fc13 [the version on the repositories does not
 load at all with wxGTK-2.8.11]
Mayavi 3.3.0-1.fc13
Python 2.6.4-25.fc13


How reproducible:
 it always happens



Steps to Reproduce:
1. run python
2. execute:
 from enthought.mayavi.mlab import *
3. the system crashes
  
Actual results:

Python 2.6.4 (r264:75706, Apr  1 2010, 02:56:02) 
[GCC 4.4.3 20100226 (Red Hat 4.4.3-8)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from enthought.mayavi.mlab import *

Warning: Unable to import the wx backend for pyface due to traceback: Traceback (most recent call last):
	  File "/usr/lib/python2.6/site-packages/enthought/pyface/toolkit.py", line 40, in _init_toolkit
	    __import__(be + 'init')
	ImportError: No module named wx.init





Expected results:
The interpreter loads the relevant classes; everything works

Additional info:
 1. running mayavi directly yields a segmentation fault
 2. running the programs from a different machine, suggests that after the
 error and BEFORE the segmentation fault there is an attempt to contact
 the xserver
 3. with wxPython 2.8.10.1-3.fc13 it is possible to run ipython-wx
 (which was not possible with version 2.8.10.1-1 of the same package)

I promise, will look into this breakage. I haven't been looking into Mayavi issues for long. Will check this weekend.

Thanks for reporting.

That is fine, thanks a lot!
 I got a complete backtrace (via abrt) of the segfault; it filed it as a different bug, though (which I have marked as duplicate of this).

Possibly related:

$ ipython -wthread
/usr/lib/python2.6/site-packages/wx-2.8-gtk2-unicode/wx/_core.py:14490: UserWarning: wxPython/wxWidgets release number mismatch
  warnings.warn("wxPython/wxWidgets release number mismatch")
Python 2.6.4 (r264:75706, Apr  1 2010, 02:56:02) 

Finally, here is the output from mayavi2 crashing:

$ mayavi2

Segmentation fault (core dumped)

Comment 6 Colin Macdonald 2010-06-08 11:40:58 UTC
More general than just mayavi, just importing wx outputs warnings:

This happens with every program that uses wx, but it was never a problem anywhere (for me at least), so I'd ignore this. (Feel free to open a new bug report to proberly update wxPython, so the warning is gone.)

The segmentation faults look similar to the one in bug #615063, so this bug should be a dublicate of that.

Mayavi is a bit outdated according to:
http://pypi.python.org/pypi/Mayavi/

I'll try to update it and maybe it's fixed in a new version.
