/var/tmp/portage/kde-base/kolourpaint-4.3.2/work/kolourpaint-4.3.2/kolourpaint/kolourpaint.cpp:125 Reported using DrKonqi
Hello, I've just found a way to reproduce this crash for sure running : kolourpaint KDE 4.3.0 Linux (i686) release 2.6.27.30-170.2.82.fc10.i686 gcc 1) Open kolourpaint 2) Select an area and move it 3) Try to write text somewhere (only select a zone, do not type any character) 4) Then undo (while the square zone for typing characters is displayed) 5) Crash
I can also reproduce this on KDE 4.4 RC2 (thanks psk!) Qt: 4.6.1 KDE Development Platform: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2)) KolourPaint: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2))
Created attachment 41436 [details] New crash information added by DrKonqi I was trying to add text to the screenshot (to report bug #229915) and suddenly kolourpaint crashed.
Created attachment 42655 [details] New crash information added by DrKonqi I added some text to my picture, pressed 'Ctrl+Z' and kolourpaint crashed (segmentation fault) Backtrace attached.
I can also confirm this bug with kde4.4 on archlinux. Just do the following steps: - open kolourpaint - write some text into a text field - press control+a - press control+z => Crash
Created attachment 47979 [details] Patch to bug #211481 This patch fixes problem (tested with steps from comment #5 and comment #1). It also fixes some compilation errors when some DEBUG defines are set to 1.
This bug happens every time when after pressing Ctrl+Z selection type changes (for example, from text selection to image selection - like in comment #1, or from image selection to text selection - like in comment #5) According to documentation (kpDocument::setSelection function), we mustn't call kpDocument::setSelection to set image selection when text selection is active and vice versa. If we must do it, we must push previous selection onto document (this is doing my patch)
