RTC 3.0 Client Failure caused by xulrunner 1.9.2.13?

I installed the RTC 3.0 Eclipse client on RHEL 5.4 yesterday after having upgraded Firefox from 3.0 to 3.6. The FF 3.6 upgrade required several package updates, including xulrunner 1.9.2.13.

I attempted to start the RTC Eclipse client, but it failed resulting in the following:

I've read from several sources the xulrunner 1.9 is not supported by RTC 2.0.0.2, however, I'm running RTC 3.0. Is anyone still seeing this behavior? If so what did you do to fix?

Thank you!
