Build Identifier: Eclipse 3.6.2

Within a product that consumes Eclipse 3.6.2 we provide the ability for our clients to submit any crashes that occur back to us.  One such crash is the following (using the IBM JVM):

Here's the javacore for the crash.

Won't be the first time something happened in the qdata code, also see bug 330476.

I've seen a similar crash on ubuntu 10.04LTS where a combobox deregistering causes a segfault around g_object_get_qdata:
