Unable to start workbench with eclipse exception

Kernel - 2.6.31.9-174.fc12.i686
OS - Fedora 12
RTC version - 2.0.0.1

When I launch RTc I get the splash screen and the progress bar seems to complete. Right after that progress bar completes the GUI fails to launch and I get an empty pop-up titled eclipse. This has been working fine for months. Only additional install that happened recently was an update to the SongBird application. Running from the command line I get the following:

Error Processing: org.eclipse.equinox.internal.p2.reconciler.dropins.DropinsRepositoryListener@7d3c7d3c: org.eclipse.core.runtime.AssertionFailedException: null argument:

I use a script to launch RTC. The script is as follows:

#!/bin/bash



export GDK_NATIVE_WINDOWS=true

/home/rodneybrown/rtc/jazz/client/eclipse/eclipse

any ideas?
