Comment 2 Francesco Riosa 2012-01-02 21:14:49 UTC 
I cannot reproduce Bug 290398 with a straigh line, but the "free hand" tool crash at the same place as the "calligraphy tool"
Comment 3 dasaan.san 2013-11-02 22:00:25 UTC 
Unable to replicate with Karbon 2.6.4 in KDE 4.10.5
Comment 4 Justin Zobel 2020-12-13 03:58:06 UTC 
Thank you for the crash report, Francesco.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.
