--- Comment #10 from Denis Kurz <kdenis at posteo.de> ---
Actually, this bug was reported for much more recent versions, although the way
to trigger it is not the same.

I think I have a rough idea what happened: When a new KMail instance is
created, its KMSystemTray is created as a copy from another KMSystemTray. This
class has a raw d-pointer, but no copy control. Now when one of the instances
is destroyed, the other has a dangling d-pointer.

That's just an educated guess, though. I'm still very confused by the gigantic
pim codebase, so I might have missed several important details.

The duplicate bug 375330 was reported for 5.2.3.
