Manfred, can you please build Kate according to http://kate-editor.org/get-it/ and report back that your issue is fixed? That would help to verify our crash fix.

Comment 2 Manfred Rebentisch 2012-03-17 06:51:43 UTC

Hi Dominik,
following http://kate-editor.org/get-it/ I startet the script with some errors:

---------------------------
I fixed that all (a trailing semikolon for "Categories").

After that I got kate 3.8.1 from git repository run and in my short tests the error does not appear.

Thank you very much! Hope, I can get the patched version for my system version soon.
