Unity restarts on icon hover

Asked by teledyn

I suspect this may be due to missing video driver support (3D or animation effects?) or some legacy configuration, but after an upgrade to 10.10 from 10.04, the Gnome desktop was fine, only after I installed and selected Unity for the default session, now the desktop will come up, only hovering over any of the left-side icons will cause the window manager to exit and re-start.

the xsession-errors reports:

software appears to run fine when run from a terminal, and the upper menu of the Unity frame still functions, this only affects the left-side icons. Could there be a package missing? Is .xsession-errors the appropriate place to look for diagnostics? Any other logs I should check?

Same here, after moving mouse from one icon to another or from an icon to the desktop, the restart occurs. It does not happen moving to an icon from outside.
