I've found a better patch.  There's a bug in dired-build-subdir-alist().
It loops through the buffer looking for lines which match
dired-subdir-regexp, but the loop breaks when the first filename ending
with ':' is found.

What needs to happen is that the filename ending in ':' is ignored, and
the loop continues.

Here's a patch.  I've left the indendation as it was to make the patch
shorter, but the function will need reindenting.  I removed a seemingly
unneeded call to save-match-data():
