Bug#255458: kmail: Serious memory corruption when dealing with multiple IMAP accounts

[Anton Ivanov <arivanov@sigsegv.cx>]

Package: kmail
Version: 4:3.2.2-2
Severity: grave
Justification: causes non-serious data loss


100% reproducible in my config after adding a second IMAP account. 

On load a replica of the second account folder tree appears in the 
GUI at random places attached under the first account folder tree 
(the normal folder tree still exists). 

Accessing the replica tree results in asking for a password 
followed by segfault. Quite likely to cause mail corruption depending
on the config.

With one account it seems to be stable (so far).
