Bug Description
This bug has been confirmed elsewhere (in the Archlinux forums). Basically, if the 'mipmap' option is enabled in EXPO or Application switcher - it will crash compiz and/or your system.
here is the Archlinux thread where users have mentioned the App-switcher crashing. I then tested it on my system and figured out that it is the 'mipmap' option that is bad if enabled;

scrolldown the page, to last 5-6 posts - it is mentioned in there.
I then tested it in EXPO - and verified that enabling it, is also very dangerous and crashes compiz.
In these cases, as far as i know - Nvidia users are affected - i don't have a non-nvidia machine to test on so i can't verfiy if it is happening with other GFX H/W.
I also have another Archer who is (hopefully) going to verfiy this on his machine (just waiting for replies from the rest, who i've told to disable mipmap in those plugins.

to add to this;
if you enable 'mipmap' in the 'static swither', it doesn't crash compiz but produces graphical artifacts;

it would appear something is wrong with the mipmap-related code in compiz. disabling it get rid of the artifacts.
NOTE: there may be other bug reports to do with these plugins, that may actually be caused by having mipmaps, enabled.
I will have a look through bug reports to see if i can find any candidates
