strace -fF korganizer: starting it and clicking around in calender views

Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

Since upgrading from KDE 4.4.5 to KDE 4.5.1 Korganizer is unusable slow on my
ThinkPad T42 with Pentium M 1.8 GHz. On a click it takes upto 10 seconds and
more with CPU usages such as 70% (the other 30% for Nepomuk Desktop search
processes + Virtuoso). I want to find a certain event by browsing the calendar
but I will now resort to grepping the calendar file.

Reproducible: Always

Steps to Reproduce:
Start Korganizer and see. I think you wouldn't have released it if did happen
on every system and with every configuration, but I do not yet know what
triggers this behavior.

Actual Results:  
Korganizer is unusably slow and uses lots of CPU time.

Expected Results:  
Korganizer is at least as snappy as it was with KDE 4.4.5.

It appears that the slowness only affects the calendar view, be it a day, a
week or a months. The task list is snappy. Once a view has been built it seems
usable, but when I click on another day it takes ages again.
