Some notes/questions:<br>
Uninstalling OpenLP is unlikely to help, you're just removing the program files
Did you remove both the data folder and the config folder? Uninstalling OpenLP doesn't touch those
What's WINE got to do with this?
I doubt Plasma will have any effect.
I'm doubtful that LVM is the problem, but I don't know what your setup is, and I have little experience with LVM
