ansi-term/multi-term error in process filter

Question

In both ansi-term and multi-term, after I cd to a directory, I get an error message and garbled output whereby the contents of ls are printed but overlaps with the prompt. This is as far as I get

$ cd /Users/crippledlambda/VirtualBoxDocuments
$ ls
  [properly shows contents]
$ cd programs
$ ls
  [properly shows contents]
$ cd newproject
$ ls
  [garbled output]

Message in minibuffer: "error in process filter: /Users/crippledlambda/VirtualBoxDocuments/prog/: no such directory"

The contents of ls are printed so it recognizes the files in the directory, but the new prompt appears above the contents of ls rather than below it, and on the prompt this text remains:

$ lsrams/newproject
$
  [contents of ls]

Do you know of this problem, or the problem or how best to debug this error? Thanks --

Sounds like a bug concerning where/how process filter messages are shown. Consider filing an Emacs bug report: M-x report-emacs-bug.
