compiz assert failure: *** glibc detected *** compiz: free(): invalid pointer: 0x00f45ff4 ***

[Jean-Baptiste Lallement]

I opened my session and had a staking problem with the switcher, opened a terminal and entered "unity --reset" to see if it improved things.

Since I didn't run the command in the background and couldn't close the terminal, I opened another tab and entered the command again "unity --reset &"

I tested alt-tab again to check if it fixed the problem (it did, at least for that session) then closed both terminal tabs with CTRL+D, this crash happened on close of the terminal
