Well, or redirect them.

I'm using a $SIG{__WARN__} handler that opens a MessageDialog to display
warning messages, a handy tool, especially for users who may not always
want to read .xsession-errors every day. However, near the beginning, it
has:
  die $message if ( $message =~ /Gtk-CRITICAL/ );
as a safety valve (since most Gtk-CRITICAL errors are caused by me making
a fairly serious mistake). The result, of course, when this bug cropped
up, was that every time I opened a FileChooserDialog, the program
mysteriously exited.

Baffled me for a little while. I began to wonder if I'd been sleepwalking
and coding at the same time. :)

So I had to install a workaround inside the handler, to prevent exits.
