I had one user experience this crash twice within first half hour of using new DIMAP account.. once when kmail was in background, and once when composing a new mail.  Backtraces are below.

Kmail version 1.9.4 (gentoo).

BJ,

Any chance you could test the newest kmail from the 3.5 branch?

And again - this time I just sent an email, and then pressed F5 from the inbox folder to force a check of mail.

BJ.

Ok, so, this bug has been reported many times, originally over a year ago.  Do you think we could get a "NEW" status instead of "UNCONFIRMED"?

*** This bug has been confirmed by popular vote. ***

SVN commit 631934 by dfaure:

Found the reason why KMAcctCachedImap::processNewMail's assert below was hit
  assert( mFolder );  // George says "better to crash then lose mail"
The configuration dialog creates temporary copies of the account when modifying one;
but it doesn't delete that copy when closing with Cancel. What's more, the copied account
started its own timer for interval-mail-checking, and when that timer fired, KMAcctCachedImap
would crash due to mFolder=0. So:
1) delete things in the dtor to avoid the account memleak
2) don't start the mailcheck timer when simply setting the checkinterval of an account,
   only when the account is added to the AccountManager for real.
BUG: 117935
