Created attachment 131651 [details] screenshot with marked area that causes the crash Reproducibly, KPA crashes, when I click somewhere on the date bar below the histogram. It even gives some sort of error message: ... [100%] Built target kphotoalbum ((then my script starts kphotoalbum --demo)) QSocketNotifier: Invalid socket 9 and type 'Read', disabling... QSocketNotifier: Invalid socket 10 and type 'Read', disabling... Unable to start Dr. Konqi (( this from my system)) Re-raising signal for core dump handling. ASSERT failure in DateBarWidget::unitAtPos: "horizontal offset larger than m_barWidth!", file /home/usr/src/kphotoalbum-git/kphotoalbum/DateBar/DateBarWidget.cpp, line 835 KCrash: Application 'kphotoalbum' crashing...

I don't know yet what causes this, but I can confirm it.
I can't reproduce this here. Can someone post a stack trace?
Johannes, could it be that the assert call is wrong? I never worked on this class, but it seems that it compares the mouse cursor position minus the left offset of the date bar with the segment width (which is 15 px in my case), thus almost always causing the assertion ...
It's caused by the Q_ASSERT_X call. I think this won't show up if a release build is done, only in debug mode.
I missed the assertion message in my first reading. Yes, the assertion is incorrect - I'll push a fix asap...
