When I install Calligra first before anything else, I got the errors.
Then I did a test where I installed Calligra after installing kdenlive, amarok, and
digikam and it worked fine.
Then I went back to a fresh install, installed Calligra first again and
once again I got the errors.
Then I reinstalled (using the reinstall option in gslapt). During the reinstall qt was upgraded to 4.8.2.
This upgrade should have happened during the first install, don't know whay it does not.
After upgrade of qt to version 4.8.2-i586-3vl70, Calligra worked as expected.
So I think that is the problem. For whatever reason when installing Calligra first it does not upgrade qt when doing the install on a fresh VL install. So depending on the state of your test box you may or may not see this problem at all.
