Installation from svn fails if backend is vtk

[GoogleCodeExporter]

What steps will reproduce the problem?
1. svn checkout http://scitools.googlecode.com/svn/trunk/ scitools-read-only
2. cd scitools-read-only
3. sudo python setup.py install

What is the expected output? What do you see instead?
Instead of the usual setup messages, I get this:

What version of the product are you using? On what operating system?
scitools Revision 511
python 2.6.4
Kubuntu 9.10 64bit

Please provide any additional information below.
I had scitools previously installed via the apt package management system.
Before installing the svn-version of scitools, I removed the package with
the normal "apt-get remove python-scitools" command.

The reason for the crash seems to be the setting "backend = vtk" in the
.scitools.cfg-file that allready existed during installation.
However, setting the backend to matplotlib for the installation solved my
problem.

Thanks for your report. I cannot reproduce this in a Ubuntu 9.10 64 bit chroot 
but I
believe that this is not a bug in SciTools. It seems to be a well-known issue 
which
is documented at python.org:

  http://www.python.org/doc/2.3/whatsnew/node18.html

However, could you try to add

  Tkinter.wantobjects = 0

after the line where Tkinter is imported (line 13) in 
lib/scitools/easyviz/vtk_.py
and see if that fixes you problem?

Thanks! That works.
Does that have any side-effects that prevents this fix from entering the 
scitools-code?

It does not seem to have any side-effects on my system so I will check it in.
Thanks for verifying that it works.
