It's possible to create a new revision, by using revert, that is exactly the same as another. If you then try and diff these two revisions, you get the following PHP warning:

warning: Cannot use a scalar value as an array in <some_path>/diff.module on line 433.

I don't know if this is the same in 6 or not yet, but I'll investigate at some point.

This doesn't seem to be the case after more investigation, but it definitely throws this error in some circumstance. I'll have to look into it further.
