Hi!

Today I crashed KMail (todays cvs) for the first time: my pop3 account (with 
interval mail checking enabled) strated to download messages at the same time 
I was writing a mail in the composer and held down the "Left Arrow" key. 
Here's my backtrace. Unfortunately I didn't compile with debugging symbols, 
so I don't know if this is of any help... :/

    rtld_fini=0x4000aa20 <_dl_fini>, stack_end=0xbffff6bc)
    at ../sysdeps/generic/libc-start.c:92

After the crash I thought I lost my (very important and big) mail, so I 
searched through /proc/kcore to get the small pieces back and together again 
(took me about 40 minutes), just to realize afterwards that KMail restored 
the mail on the next startup! WOW!! That is really the best feature I have 
ever seen in a mail client :-))

Ciao,
  Michael
