Sentry Crash Report:

Description Davor Cubranic 2012-01-23 19:15:51 UTC 
Application: akonadi_imap_resource (4.7)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 2.6.38-13-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
I created a new IMAP account, in which mail folders are kept under "~/Mail". There was no way to configure that in the account setup dialog, so KMail tried to treat every file and directory in my home directory as a mail folder (this is reported as bug 292285). Eventually, akonadi crashed trying to index all the gigabytes of files.

-- Backtrace:
Application: UBC-CS of type IMAP E-Mail Server (akonadi_imap_resource), signal: Segmentation fault

Comment 1 Jon Williams 2012-01-26 16:45:02 UTC 
Not sure if I've got a duplicate.

I'm now trying to clear it all off the system and start over, however the misconfiguration that prevents load of kmail doesn't allow me to change settings. Looking at email threads it appears to be all in akondai or whatever...but can I blow the database away and start over?

Kmail is totally unusable across upgrades etc...crashes on start (using kde 4.72 now too (tumbleweed on Suse)
Comment 2 Davor Cubranic 2012-01-26 23:24:23 UTC 
Jon, I'm pretty sure you can, but don't know how. You'll need to ask for guidance somewhere else.
Comment 3 Gulraj Rijhwani 2012-02-09 13:57:59 UTC 
I have a very similar problem.

Just made the jump step from Fedora 14 to 16, and now Kmail (4.7 from 4.4) insists on Akonadi indexing all the mail, which it simply is not man enough to do.  This was AFTER having to figure out that Kmail, having performed an automated "migration" had failed to give Akonadi a path for the local mail folders, and kept crashing out.

This machine has 2GB of RAM and 2GB of swap - Akonadi grows to use it all until the the synchronising process trying to regrow the indexes (/usr/bin/akonadi_mixedmaildir_resource --identifier akonadi_mixedmaildir_resource_0) is assassinated by the kernel, leaving Kmail without all of my organised mail folders from the last 5 years.  It's less than useless - I have lost access to some very important historic messages, and I cannot even read critical current work email...
Comment 4 Kevin Ottens 2012-02-11 10:40:21 UTC 
Would need at least a complete backtrace, this one is unfortunately incomplete, please install the debug symbols on your machine (your distro provides that AFAIK).

Also please test again with 4.8.

The IMAP resource has a new maintainer, reassigning to him.
