Description Roel Meeuws 2007-01-23 13:01:37 UTC

Version:            (using KDE KDE 3.5.5)
Installed from:    Ubuntu Packages
OS:                Linux

When I start up kmail I first get a kwalletmanager dialog. In the background I see I still have 2 unread emails, which is correct I had still 2 emails open. Then I enter my wallet password. Directly, kmail says there are 65 unread emails and actually, previously read mails are now marked unread. Then within 2 seconds or so, kmail crashes with a segmentation fault. 

First I thought there was something wrong with my gmail pop settings, so I deleted that from the kmailrc file and then the kwalletmanager didn't pop up after startup. Furthermore, I got the message to add an account. after clicking ok on that dialog, the same error occurs. 65 messages seem to be unread and the application crashes. The following trace was generated. Mainly the last few lines might help:

*** Bug 140491 has been marked as a duplicate of this bug. ***

Comment 2 Roel Meeuws 2007-01-27 17:49:52 UTC

Solved it by removing searches. then trying a search on each folder and then searching the folder that crashed the app. There was a mail that was empty. I removed the mail and voila everything was okay again. Somebody should fix this, it shouldn´t crash when an email is not okay. I attached the culprit for your review.

Comment 3 Roel Meeuws 2007-01-27 17:51:39 UTC

Created attachment 19443 [details]
the mail that crashed kmail

This is the email that crashed kmail when the search thread opened it.

Comment 4 Greg Martyn 2007-09-21 18:27:02 UTC

I got hit by this bug too. Happens every startup at the same place. I don't have time to use the GUI before the crash. Here is a more detailed backtrace:

Comment 5 Greg Martyn 2007-09-21 18:36:05 UTC

Was able to work around it by deleting my stored search for important mail. I'm going to miss that one..
