(I'm going through old bug reports that unfortunately weren't resolved
at the time. And my apologies if you get this message twice.)
I don't think this is a bug. AUCTeX doesn't handle the arguments of
\includgraphics or \bibliography as verbatim text, in contrast to
\verb|$HOME/path/to/graphic|. So AUCTeX provides the %$ trick at the
end of line as a solution for your use case.
Therefore I'm closing this report.
Best, Arash
