So. Sadly enough I can't reproduce here with kde from svn trunk (which should not be too different from kde4.5 yet). Anyway. Commits from Comment #2 should help. Keep me posted if this still occurs (with either trunk or rc2), as there are other protections I could put in (but am reluctant too since this is extra overhead). Or close the bug if it dissapeared.
I just updated and it works flawlessly. Tnx guys.
Awesome ! I'm closing the bug report then.
