plasma crash in tooltipmanager

[David Faure]

KDE-soon-4.2.

I was clicking in the taskbar to switch to another window when a window just appeared,
or something like that -- some kind of race between the taskbar and me --, and plasma crashed:

Looks like an already-deleted applet, but this can't be, I wasn't removing any applets,
there were just taskbar entries coming and going...

PS: please cc me in case of replies, I'm not subscribed.

Application: Plasma Workspace (plasma), signal SIGSEGV
