Sorry, I'd forgotten: there is a bug in imaxima.el which makes it intolerant
of spaces in the path to imaxima.lisp.  The error you got is not exactly the
same as the one I encountered in the past, but perhaps these are different
versions of imaxima.el  I corrected this in imaxima.el and emailed the issue
and fix to the imaxima maintainter, but I'm not sure that he's implemented
the patch.  Below is my email regarding the problem and the fix.
