When invoking browse-url in a buffer where the default directory no
longer exists which happens quite often if you have long-running emacs
session, the following error is generated and browse-url aborts the
action.

Debugger entered--Lisp error: (file-error "Setting current directory" "no such file or directory" "/Users/leo/Desktop/untitled folder/")
  start-process("open http://paste.lisp.org/display/98663" nil "open" "http://paste.lisp.org/display/98663")

I wonder if it makes sense to make start-process more robust in this
case. Thanks.

Version: 24.1

This crops up in a few places. I have a vague memory that there is some
problem with/opposition to a general fix. Installed a fix for
browse-url.

Yes, there is risk in setting a new default directory.

They were discussed in the followup to:
http://permalink.gmane.org/gmane.emacs.devel/135971

But I can't seem to find the thread.

There is opposition to fixing it in start/call-process since it does the
wrong thing if the command uses to relative filenames.  There is no
opposition to "a general fix" at all, although such a general fix would
look like a macro that can easily be added where useful/needed, or maybe
some additional arg, or clever reuse of existing arg.
