The only problem I am having is with newest version r30427. I am getting this error when I leave a party but doesn't seem to cause any other issues that I can see but I am not raiding and looks like that is what the error is referring to and maybe what the others above are having issues with?
I'm also having quite a bit of problems with ag_uf as of late. Can't say exactly what release caused my player frame to start acting up but it's the same (maybe even worse) in r30476. Basically only way I can click on it is if I move my mouse on the border under the mana bar (I have xp and cast bar disabled). All other frames can be easily selected, they highlight when I mouse over them. Other really annoying thing is that now when I change any option for frames (bar texture, width, border, layout.. anything really) it does not update until I reload my ui. Considering that I just nuked my saved variables to make sure they are not causing the problems, configuring the frames is kind of impossible right now.

You're not alone, I'm having the same issue with the Player frame. It seemed to have started within the last few weeks.
I'm having problems after I updated today to rev 30476 regarding the party frame not showing all people (just slows a black/grey background) and not actually being able to change any settings at all on any of the frames. Guess i'll be setting my frames up yet again :(
