Comment 34 for bug 975503

Looks like the XSetInputFocus call (causing the error):

002:<:1394: 12: Request(42): SetInputFocus revert-to=Parent(0x02)
focus=0x0460044e time=CurrentTime(0x00000000)
...
002:>:1394:Error 8=Match: major=42, minor=0, bad=73401422

is this one:

*but* - it is surrounded by the error trap push/pop:

unx/gtk/window/gtkframe.cxx- GetGenericData()->ErrorTrapPush();
unx/gtk/window/gtkframe.cxx- XSetInputFocus( getDisplay()->GetDisplay(), widget_get_xid(m_pWindow), RevertToParent, CurrentTime );
unx/gtk/window/gtkframe.cxx: GetGenericData()->ErrorTrapPop();

Possibly we are missing an XSync in there ...
