[Kde-pim] akonadi resource processes crashing (in masses)

[Andreas Hartmetz]

Hi,

Today I noticed about 40 core files of dead akonadi resource processes in my 
core files dir, after cleaning that dir yesterday (it contained about 70 
resource process core files at the time). They crash in KPixmapCache which, 
frankly, needs to be killed with fire better sooner than later. The current 
implementation that is.
Anyway, akonadi processes crash because of it. I hope you can do something 
about it...
Here's a backtrace.

Core was generated by `/opt/kde4/bin/akonadi_maildir_resource --identifier 
akonadi_maildir_resource_14'.
Program terminated with signal 7, Bus error.
