[Bug awt/23951] New: gtk peer crash in awt testlets

[david at lichteblau dot com]

Classpath 0.18 (on JamVM) throws an InternalError ("GLib-GObject: invalid (NULL)
pointer instance") when Mauve AWT tests are all run consecutively in the same
test harness.  (See attachments for the precise test names and error message.)

The problem appears to be a race condition, because it does not happen always. 
(About every second time for me.)

The same tests work fine when a new VM started for each of them.

After printing the error message, the thread hangs.  Attached a patch does
"solves" the hang and makes mauve report success -- but does not change anything
about the actual NULL pointer problem.  Not sure if the code path patched here
is supposed to be taken, but that is what seems to happen.
