Description Jan 2012-03-10 13:29:47 UTC 
Application: kmail (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
i started kmail instead of kontact, as kontact behaves extremly slow after upgrade to 4.8.1 with kubuntu backports 11.10
reading and moving mails worked, but when i clicked on New Mail button the application crashed

- Unusual behavior I noticed:
mysqld and virtuose-t process takes very much cpu. KDE at all seems very unstable after the upgrade to 4.8.1

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault

Reported using DrKonqi
Comment 1 Jan 2012-03-10 22:07:59 UTC 
this crash is caused due to usage of nepomuk. with disabled nepomuk this does not happen.
Comment 2 Jan 2012-03-10 22:26:19 UTC 
seems like it is only the nepomuk mail indexer.

With enabled basic nepomuk this crash does not happen.
Having file indexer enabled works fine.
Using nepomuk mail indexer causes this crash every time i try to compose a new email.
Comment 3 Jan 2012-03-11 08:36:38 UTC 
Its me again. Kontact is crashing on composing a new mail every now and then even if only basic nepomuk is running.
Comment 4 Jan 2012-03-14 17:29:23 UTC 
This now seems to happen even with nepomuk completly disabled sometimes. Replying to a mail seems to work.
Comment 5 Jan 2012-03-22 18:14:19 UTC 
this doesn't seems to be nepomuk related.
I deleted any nepomuk files but this still happens. Even with disabled nepomuk.

Kmail is unusable at the moment

New crash information added by DrKonqi

kmail (4.8.0) on KDE Platform 4.8.1 (4.8.1) using Qt 4.8.0

- What I was doing when the application crashed:

When I click the New button in Kmail and I have the %SIGNATURE macro set in my new message template, I get a crash.

When I leave the %SIGNATURE macro out of the template, Kmail does not crash.

I am able to add %SIGNATURE to the reply template without a crash.
