additional Netscape error symptoms - Xlib: unexpected async reply

[Daniel Barclay <daniel@dsb.smart.net>]

Has anyone else seen this problem?

Sometimes Communicator will pop up an error message window so small that
the only thing visible is the window manager's frame around it.

When I expand the window, it has about a dozen copies the following
message:

   Xlib: unexpected async reply (sequence xxx), Netscape:
   subprocess diagnostics (stdout/stderr)

This is inevitably followed by another vanishingly small window, with
another bunch of the same type of message.


Communicator quickly proceeds to becoming unresponsive.  (I think
sometimes I can quit and get any changes (e.g., bookmarks) saved 
before it jams up.)
