Application: kontact (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-17-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: Opening a new email

- Unusual behavior I noticed: Kmail deleted the content of newly arrives messages on the server (laposte.net) leaving nothing but the header - and on another server (gmail.com) created an empty copy (message with header but no content) for each message.
I have been in contact with the maintainers at laposte.net and it turned out that it is actually kmail that deletes the message content - new messages were unaltered by Firefox, Konqueror and rekonq when I used the webmail only and did not open Kontact or Kmail.
These errors reproduced since March 24, when I upgraded to KDE 4.8.1., through the repositories of Kubuntu 11.10 (oneiric). There were no errors prior to the upgrade!

One fatal error message stated that "Timeout wants to get a lock". This showed several times, including the crahreport filed here!

The crash can be reproduced every time.
