concerned about this error

[cake nom nom]

got ubuntu 10.4 32bit
-im using emerald
-i have Cairo dock but i use the noopen gl version

while trying to find a reason to why my animations wernt working (which i fixed by going into the main animations setting going to the effect settings tab and checking random animations for all events)

i discovered the following error and now im quite concerned now

if i type in compiz into the terminal here is my out put

drnomnomcake@drnomnomcake-laptop:~$ compiz
