Short description of error
Bringing up an existing *.blend file. using tab to switch between edit and object mode, causes crash or hang enough to require machine to be turned off and on to recover.
Exact steps for others to reproduce the error
This is a little intermittent in that I can't just do this from the clean start up. Open attached file, tab a time or two and it will hang up blender and possibly even the whole Gnome desktop.
[Based on the default startup or an attached .blend file (as simple as possible)]
