The attached patch fixes it for me. The cause seems to be that the
returned alist for a directory browser has entries for (directory
...) and (Last-Modified ...) and the code was only getting rid of
the former only. That leftover (Last-Modified ...) would then trip
up the assert in mpc--proc-alist-to-alists when it checks with
mpc--proc-alist-to-alists-starters.
