This problem is not fixed in rev 71123 on Solaris 9 on SPARC.
Reopening report.

Another way to reproduce this same crash is to type Ctrl+Tab
and then click on a the name of a tool in the resulting
popup window which is in Auto Hide mode and which
is not currently visible (e.g., the Metrics tool in the
default configuration).  I just did this on rev 77123 and
got the same or a very similar exception trace.
