The backtrace is unfortunately rather useless as it's missing the debug information. As you are able to reproduce at will, please install/compile the debug packages and attach a proper backtrace. Thanks here it is .. i hope.
i had forgotten to compile qt-gui and qt-core with gddb last time.

thanks - that was fast (in most cases we do not hear anything from the users any more if debug symbols are missing). The crash could be a duplicate of bug #233363, but it is difficult to say as desktopgrid seemed to have quite some code changes in 4.5 ;-) --- thanks - that was fast (in most cases we do not hear anything

no problem doing my bit to help :D
also this is how i reproduce the bug
1)enable the desktop grid plugin and set the layout to pager.
2)Make sure you have only one virtual desktop
3) activate the desktop grid and click on the blank space below the virtual
desktop (shown in the attached screen shot of the pager layout). kwin will now
zoom into the black space and then immediatly switch back to the actualy
desktop.
4) keep repeating step 3 till kwin crashes (arround 5-7 times is usually
enough).
*** Bug 249137 has been marked as a duplicate of this bug. *** there is a bug in the pager: it leaves number of rows at two if there is only one desktop. I will add a sanity check to desktop grid to prevent this crash. SVN commit 1169040 by graesslin: Add sanity check to DesktopGrid in case of pager layout and only one desktop. Pager reported two rows, which does not make sense and caused the grid to be in an inconsistent state.
