Comment 1 Jekyll Wu 2013-09-19 06:11:48 UTC 
Sorry, your system and KDE/Qt installation is quite old. Please try recent version (KDE 4.10.5 or 4.11.1, Qt 4.8.4 or 4.8.5) to see whether the problem still exist.

Comment 3 Jekyll Wu 2013-09-28 00:16:17 UTC 
your two crashes are unlikely related. 

The first crash from Ubuntu is probably due to a Qt bug (that is why I suggest you tyring some newer Qt installtion), but the second crash from Gentoo shows that your system fails to load some dynamic library (usually indicates a broken system after some upgrading)
Comment 4 Joachim Langenbach 2013-10-13 18:03:31 UTC 
Have run revdep-rebuild, which detectes broken libraries and recompiles them. Afterwards kleopatra crashes the same way as before. drkonqi says, that no useful crash dump could be created. But the error with glibc is shown on terminal.
