Subject: Fix crash on double-click in Game List Tags
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=60082806a890461944c2f6b5d424ec659b23001a;p=xboard.git

Fix crash on double-click in Game List Tags

A double-click in the Game List Tags listbox has no function, but it
crashed XBoard, because the textValue field of teh ListBox Option definition,
supposed to contain a pointer to the user-supplied handler, contained a
pointer to an empty string.
