Error when using VaxStation as terminal

[Kevin Handy <kth srv net>]

I am using a VaxStation 3100 (GPX) as an X-terminal to a
RedHat Linux box, and have found that the 'clist' widget
will crash consistantly, usually with an error like the
following:

Gdk-ERROR **: BadValue (integer parameter out of range for operation)
   serial 560 error_code 2 request code 61 minor code 0

Going through all of the programs in the example directory
of gtk+-1.2.2 all work except for the 'clist' and the
'filesel' examples (which I'm guessing uses clist).

What does clist do that would cause a crash when none of
the other widgets seem to have a problem?

Backtrace doesn't show function names in the gtk stuff,
(used the normal compile process) but here it is for
the 'examples/clist/clist' example, which displays a
blank list, but dies when I try to do anything:

Core was generated by `./clist/clist'.
Program terminated with signal 6, Aborted.
