I had the same problem when using an ATI X600XT (w Callisto for QE/CI) but it all went away after I switched to a working X1600 instead. (Well it also crashed for me)
I can see two differences here. First, there are different drivers used for the X600 (including third party un-finished drivers) and second I had to use older drivers and (OpenGL) frameworks with the X600 whereas the X1600 uses the drivers/frameworks from my current OS X version.
Maybe there is a problem with QE/CI not being fully OK with Callisto or there is a problem when using drivers that are of a different version than the rest of the system??
Probably not the input you were looking for I guess.
This was very helpful to me. I am having the same problem, with iMovie, and also iDvd, Pages, and KeyNote, my graphics card is unsupported, but I have an X1600 coming in the mail soon, I'll let you know if it works out, thanks!!
