I have the same problem in Ubuntu 11.04 i 386
Step to reproduce it:
1) Open LibreOffice Writer 2) Add a picture (Insert> Picture> From File ...) 3) Move the image around
Suddenly the bar is shown and Unity will no longer disappear. The only way to make it work properly is to close LibreOffice Writer
