Berkeley DB Family

I sometimes get the following error when trying to call (as part of a new development version of my XqUSEme extension in Firefox), the XmlManager constructor with an Environment and XmlManagerConfig object.

I have been able to get BDBXML 2.3.10 to work with Firefox 2 and 3 (now FF3 RC1), but version 2.4.13 only works in Firefox 2 (I didn't test interim versions). The above error only sometimes occurs, so I'm guessing it might relate to processing timing somehow (whether in the Java or C++ API or in Firefox's JavaScript/LiveConnect interpreter), perhaps because Firefox 3 is faster (but again, BDBXML 2.3.10 works in FF3 too, so it can't be all of FF's issue)?

Anything you think I can do about it?
