Crash in KonqMostOftenURLSAction

[Jonathan Brugge]

Ok, I've been trying for hours to crash it in Valgrind, but it just doesn't 
want that. The moment I tried it in a Konqueror-window that wasn't managed by 
Valgrind, it crashed...quite frustrating. Anyway, here's the backtrace. I'm 
posting it because the crash didn't happen when opening a new window, but 
when viewing "Go => Most Often Visited". The problem obviously isn't in 
creating a new window or clicking a link - but that's all I can say about it.

Offtopic: while running Valgrind, I managed to crash Konqueror at some other 
point. I've attached the logfile (gzipped, since it's 33kB in a plain format) 
in case you want to take a look at it. There's a backtrace too (not 
attached), but it doesn't contain much useful information - some valgrind 
calls, no calls made by Konqueror directly.

P.S.: would it help if I built a Qt with debug-information too? If so, I'll do 
that - but it'll take some time, since rebuilding Qt is not blindingly fast 
on my Athlon 700.
