If I have a project containing a psudocoloured image in 1.8 and then try to load it in 2.0 I get a crash with the following traceback:

I can replicate this by creating a small palletted image in 1.8 (which loads fine there) and then trying to load it in QGIS master (which crashes). I have made a test to demonstrate this which I will reference in this ticket shortly.

I've made this ticket a blocker as it instantly crashes QGIS when loading many valid older projects which is not a good user experience.
