Is QuickAccess Browser, not Quick Launch. Sorry.

Comment 6 lnxusr 2010-06-10 17:52:43 UTC
I Just installed 4.5 beta 2 from the ppa repository, and this is happening to me as well.  Every time I click on the Quick Access Browser, Plasma crashes and restarts.  I'm getting no notification or popups, it just restarts itself and off I go on my marry way (as long as the merry way doesn't lead back to clicking Quick Access Browser again)..

I have no backtrace info to give, as I said I get no notification dialogs.  Plasma just quietly restarts.

Hi
Just a small report from downstream,we are working on correcting this package for Kubuntu Maverick and might backport it to the PPA,please remove the plasmoid for now till a fix is released.
