The only problem I've ever come across that causes this to happen is 
that MIB-files are installed that aren't readable by the Nagios user, 
and the testing is done manually as root.

Is that perhaps the case here too? You should always run the check 
manually as the same user as nagios runs as, and please mention it when 
reporting bugs if that's the case.
