Bug 227527

Application that crashed: kmail
Version of the application: 1.12.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Updated password on my IMAP account.  Think I succesfully updated kmail password but next time logged in it presented Authorisation Dialogue and what ever I do (correct password, incorrect password, cancel) kmail segfaults with signal 11 and I cannot read my mail.

This is repeatable everytime I try to open kmail.  Rebooting doesn't solve anything.  Problem persitant for at least one week.

using (K)Ubuntu 9.10

I can see many similar reports on the kmail system which might be related bug 225086 for example and possible several other bugs that have been marked duplicates of 184324 but no action.  Some help would be appreciated.
