This is most probably your error, not babel bug. Most LaTeX packages
contain internal macros with names similar to \@something. When a
package is loaded by \usepackage or \RequirePackage, the category of @
is set to 11, which is a letter. \@something is then a series of
letters and thus forms a valid cseq name. Outside packages the
category of @ is 12. In that case \@something is considered to be a
short control smbol \@ followed by characters something. The meaning
of \@ is a space factor. This is the most frequent reason of such
errors.

Could you provide the minimum sample producing this error?
