I still think that overlapping handlers *should* work: if they don't
it should be fixed. After all, jka-compr and ange-ftp do overlap.

Sounds like a bug. Can you show a backtrace ?
[ the code in find-file-noselect seems to be careful to avoid expanding
wildcards repeatedly, so the problem must be in file-expand-wildcards,
which could possibly loop forever if applying file-name-directory
directory-file-name repeatedly loops. Does it ? ]

I do think using [...] is a rather poor choice since it collides with the
wildchar patterns. How about using parens instead ?
