It seems legitimate, although the \"100x100>\" part looks suspicious
(what is that '>' character doing there?).  But I don't think this is
the problem.

It's the $HOME part that is the problem.  Can you find out where
exactly inside image-dired-thumb-name does it come from?  The $HOME
part was supposed to be expanded, but instead it is being treated
literally, and the current directory is prepended to it.  The question
is, what code produces that.
