Dash doesn't work...

[orange2k]

When I click on dash and then on "more applications" nothing happens,
the screen is blank, so I don't have access to my other applications anymore...

What should I do?

You could try this command
unity --reset-icons

I would like to do that but I can't even start the terminal...

edit: I managed to access the terminal by going to unity 2d and then dash worked, but its still pretty buggy it seems...
