[Kdelibs-bugs] [BUG] Crash in Download Progress

[Allen Winter]

Howdy,

When I click on a URL embedded in a KMail message, the download progress popup 
starts but then KMail crashes almost immediately.  Attached is a backtrace.

I can't make much from the backtrace, but maybe the gurus can make some sense 
of it.
