from kde-testing, I get crashes of Kmail.  Kmail does not display
messages in the preview window any more and crashes after exiting the
app and intermittently under other circumstances.

Many stack traces are marked "This backtrace appears to be of no use."

How to reproduce (blank preview):

Start kontact(kmail).
Click on mail folder containing messages.
Preview panel is blank.

How to reproduce (crash):

Start kontact(kmail).
Exit kmail.
Crash.

Here's a trace after closing Kmail with ctrl-q:

Application: Kontact (kontact), signal SIGSEGV
