Bug 96783

Version:            (using KDE KDE 3.3.1)
Installed from:    Debian testing/unstable Packages
OS:                Linux

Once in a while, doing a simple copy&paste within a file, kate segfaults and dies horribly. To reproduce the problem load the file 'tryout.py':
-------tryout.py--------
.l()
.if.f:
..break
------------------------
(replacing . with space and including a newline at the end)

mark the complete text, copy it and paste it to the end of the same file.

>>>> crash!

I have the feeling that the problem is connected to the folding of the text and/or Python syntax highlighting.



The backtrace starts out with:
