Comment 1 Halla Rempt 2012-08-29 07:14:13 UTC

Thanks for your report. I'm not too sure what's going on here -- it must have something to do with the text tool. It seems you were using that when switching windows, but how that can cause this crash, I don't understand yet.

Comment 2 Halla Rempt 2012-09-27 13:24:59 UTC

Hi Marko,

I'm afraid I'm going to have to close your report. I'm grateful that you took the effort to report the issue, but by now we're working on Krita 2.6 and I haven't been able to reproduce this issue. There have been several fixes committed to the artistic text tool, and those actually might have fixed the issue already.
