Bug 316112

Application: calligrasheets (2.6.0)
KDE Platform Version: 4.10.00
Qt Version: 4.8.3
Operating System: Linux 3.5.0-25-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:

I was changing the background colour of a single cell using the "Cell format" dialogue. I clicked on the "choose colour" button and used the "recent colours" feature of the standard KDE colour dialogue. On clicking the desired colour, the crash occurred. The only odd thing that I noticed was that my most recently selected colour (pale yellow, if that helps identify which entry in the dialogue I clicked) was repeated several times in the recent colours palette, even though I had only used the colour once (i.e. the last time I used the KDE colour dialogue was to choose this colour for some other cells a few minutes previously and at that time I selected the colour using the HSV block, which is how it came to be in the recent colours list in the first place).

During my current desktop session, Calligra Sheets is the only application that has used the KDE colour dialogue.
