After trying and trying and trying to get to grips with the buggy Unity I finally gave up and returned to Ubuntu Classic. However after using it for 12 hours half my Places have disappeared from my drop-down menu.
The only explanation for the disappearance is that whilst doing something non-specific, Ubuntu crashed. Indeed Ubuntu appears to be crashing regularly, about once a day, since upgrading to Natty. It is completely random though.
Despite rebooting my Places menu is still missing things like Documents, Music, Video etc. Where are they, any ideas?
