Hi, if this is reproducible, please provide a backtrace. For more information, see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

I'm not sure if it's the exact same bug, but I have a reproducible bug related to use of Undo.  It crashes KolourPaint with a segmentation fault.  I'd be glad to provide a backtrace, however I'm not sure how to install debugging packages.  The KDE Crash Handler when I click "Install Debug Symbols" tells me:
-----------------
Error during the installation of debug symbols -- The...
Could not find debug symbol packages for this application.
-----------------
According to http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports
Ubuntu packages are all supposed to have "-dbg" counterparts, however when I tried:
---------------
sudo apt-get install kolourpaint4-dbg
I got:
---------------
E: Unable to locate package kolourpaint4-dbg
-------------------------
To reproduce the bug in Kubuntu 12.04 (KDE 4.8.5) with version 4.8.4 of KolourPaint:
1) Start KolourPaint
2) Paste an image onto the existing canvas.*
3) Press 'G', or click the freehand polygon tool.
4) Click on the canvas 3 times.**
5) Click Undo...Undo: Selection: Create***
6) Press 'M', or click the freehand selection tool.

Notes:
* I've tried multiple pictures with different sizes, so any pasted image should do.
** Do NOT right-click or select any another tools between steps 4 and 5 above!  The polygon must be drawn, but not finalized.
*** For Step 5, you can click the Undo on the toolbar, or go to Edit...Undo, but using Ctrl+Z doesn't work, since it finalizes the polygon.

Here is the "not useful" crash information:
--------------------
Application: KolourPaint (kolourpaint), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
