Comment 2 Dominik Haumann 2012-10-24 23:23:01 UTC

Adrian, can you have a look again here? You probably find this issue much better than us! Would be awesome :)

Comment 3 Christoph Cullmann 2012-10-27 11:28:32 UTC

We need a testcase for this, else we won't find it, sorry :(
I you could provide a file and some steps to reproduce, we will take a look.

Comment 4 Thiago Jung Bauermann 2012-11-27 02:25:52 UTC

Bug 309846 has a very similar backtrace (the top 4 frames are identical), and in both cases KateIconBorder::paintBorder is involved. So perhaps they are related?

The reporter of 309846 can reproduce the bug everytime, by editing patch files. I was able to reproduce the bug using his method too (besides editing the patch and undoing and redoing, I had to save the file every now and then).
