For what it's worth, a quick band-aid for me was to take the plugins/place/place.cpp and plugins/place/place.h from the 0.9.6 (Oneiric) source tree, put them in the 0.9.7.8 source tree and re-compile.
You lose whatever bugfixes and tweaks came with the new version, but it fixes a number of problems related to this bug, such as fullscreen flash video getting pushed down by the panel.
