Well I found the culprit, even though I must admit I don't know what to do with it.
I moved each file that was listed under the directory /egroupware one by one then once all the files were moved I started to move each subdirectory in their entirety. When I moved the directory phpgwapi I got the error. When I moved it back out the error went away. I could send you the directory as a tar if you thought that would help. Let me know.
