holck, your configuration looks like mine, but I don't have this problem, even though I don't have libqpepim.so.1 either. Are you using version 1.9.5a of KDE-Pim? If not, try backing up your data, uninstalling everything to do with KDE-Pim that is an earlier version, and upgrading to 1.9.5a (except for the alarm applet, which should be 1.9.4).
Even if you think that you are using 1.9.5a, you may have forgotten to upgrade one of the packages. I suggest that you double-check carefully.
Hope that this helps,
P.
