Hi! First you should try with a clean KDE configuration (for example a new test user): it looks the transition from 4.4 to 4.5rc1 is not stable, probably from 4.4 to 4.5rc2 could be better. Anyway, can you reproduce with a clean configuration?

And what does it happens if you update to rc2?

Hi, with a new testuser it's same, also with RC2 and clean conf.

KDE 4.4.92 (KDE 4.5 (RC2))

P.S. Just for info the "workspace type" is configured to "Desktop".

Thanks Daniel. Just for being sure I've tested the opensuse packages and a clean user but I cannot reproduce. I leave the status bug to "unconfirmed".

Hello again,

today I closed that window again (with RC2) and "Plasma" was killed but in this time was restart automatic and gived to me following message:
