w3/widget bug

[Colin Rafferty]

I am sending this to all semi-relevant parties.

Description of Problem:

When hitting a button on a link, I get the following backtrace.  I
imagine it has something to do with the new `widget' that comes with Red
Gnus, but I cannot be sure.

---------------- begin backtrace ----------------

I answered this in the wrong thread. [ No Danger ]

It looks like a bug caused by using an old w3 version together with a
new Gnus.  The _push_ widget was renamed _push-button_ at some point.
