I though this bug had already been fixed (Stefano Iacus reported it to me
a while back). The problem occurs when a variable has a set of factor
names assigned, but that set of names is not present in the file -- it was
not clear from the otherwise excellent Stata documentation that this is
possible in a valid .dta file.
Obviously the fix is not completely effective. I'll look into it.
