Bug 262743

We've first seen this problem on the morning of 07.01 on one device.
On another device the same version with no deleted configuration/data did not have the problem. 
The first device could be fixed by replacing akonadi_agent_server with a reldebug build.

I've replaced the binary with a reldebug build on my phone, restarted (with akonadictl) and deleted everything, still no sucess.

After that i've restartain again started again (with akonadictl) this time without deleting the configuration and i have a usable setup now, local folders are shown.

FWIW: I could remove 20110105-0628 without problems.

Moved this up to critical since i can not find a reliable workaround and it blocks further testing.

Some additional info:
Test setup to reprodce is always -> Restart device -> Remove all config -> start (with akonadictl or kmail or direclty does not matter)

Backtrace: (Apologies for the gaps and the bad formating but this comes from Visual Studio and is the completes i could get)

---------------------------------

After the same procedure with the deleted korgac desktop file it did not crash but there were no mail folders shown in Kmail, although the local maildir account was shown under accounts but not as online.

What i have also tested was to comment out all agents except for maildir. This changed the behavior in the way that no agent was loaded in the beginning.

(Starting akonadi_agent_server after that starting akonadi) 
When i then started KMail i got an error that the akonadi_contacts_ressource was not available. Then i got a message that it would load the maildir ressouce now and after that i got a DataAbort in qtcore.

should be fixed with svn 1214159, this just removes the trigger, course is not found yet.

Cause was the duplicated instance of dlmalloc that came with aspell and was linked statically with the akonadi agent server. (which also uses dlmalloc from qtcore) 
Making aspell also use the dlmalloc from qtcore this problem was solved.
