Bug 138846

Version:           kdepim-kmail-3.5.4-12mdv2007.0 (using KDE KDE 3.5.4)
Installed from:    Mandriva RPMs
Compiler:          as distributed with Mandriva-2007 Powerpack 
OS:                Linux

kmail creates multiple
duplicate messages in imap inbox account, then deleting duplicates crashes but not always(!) kmail. 
The multiple messages are result of spamassassin filter as they all differ in just one line:

X-UID: 
The number following this (e.g. X-UID: 4761) is different.

So what is likely happenning, the
filter adds this line to the message (or rewrites the existing X-UID), kmail decides it's a new message and
syncronises it with the imap server on the next retrieval of messages creating a duplicate on the server (I
checked that!), the filter then runs again etc. entering in the loop and kmail eventually gives
up.

Here is
the backtrace of the crash:
