@Dibcsi: that's kinda what you get when you flash unofficial firmware into a device that's not supposed to be running it. Most apps found in the extra* repositories right now are made for PR1.1.1. If any of them use a lib that's been updated in PR1.2 (such as the librtcom suite) then you'll have trouble running them.

As for a fix: a while back one Extended Call Log version was mistakenly built against the PR1.2 libs, and I think it can still be found in one of the extra* repositories.. I think it's devel, but I'm not sure. Fire up the app manager, uninstall the version you currently have, activate only one of the extra repositories at a time and look for the app again. Install the one that doesn't report any problems when you press "Details".
