Just installed 0.8.2 via builder wizard. Works fine the first time except after reopening the next time, the Project Tree is visible but grayed out and unusable. Everything else seems to work fine; the timeline, the project monitor, effects, transitions, etc. Can't use the Project Tree to add or edit clips. The Project Menu will add clips but one can't verify whether it did or not because the Project Tree does not work. It just sits there like a photograph. I tried deleting the kdenliverc file but no change.
I went back to an earlier revision in 0.8.1 and the Project Tree worked fine.

Anyone else experience this? Just curious before I submit a bug report.
