Athena "search" dialog hosed

Given the history of Athena-related problems, the subject line is probably no news for Andy. Still, I'd like to report the problems. When I click on the "Edit->Search..." menu entry, I get a nice little dialog. However, although the dialog gets WM focus, I can't type anything because the characters end up inserted into the XEmacs frame. I managed to trick XEmacs by selecting some characters with the mouse and button2-pasting them into the dialog box. At that point, when I press RET nothing happens. When I click on the "Find next" button a few times, XEmacs crashes. This is on Linux, a freshly built debugging XEmacs from the latest CVS + Yoshiki's "Fix crash by make-search-dialog" patch.
