Segfault with tktreectrl on python-2.5 on linux

[klappnase]

Hello,

I use the tktreectrl Tk extension (http://tktreectrl.sourceforge.net)
through the python wrapper module
(http://klappnase.zexxo.net/TkinterTreectrl/index.html).
With python-2.5 it seems that each time some text is inserted into the
treectrl widget a segfault occurs (on linux, on windows2000 it seemed
to work).
Some people sent me mail describing the same problem, so I think it is
not a problem with my installation of python-2.5. The treectrl widget
itself works well when running from Tcl or from python2.4, so i suspect
that it is a bug in python-2.5.
Below the output from gdb when running the dirtree demo from the
TkinterTreectrl package:

(gdb) run

Any ideas?
