Problem running ScalaTest tests after latest update (0.5.800)

Hi guys, thanks so much for your work on the Scala plugin.

Just updated to latest version, and getting an exception while trying to run ScalaTest tests:

<<removed lots of stuff>>

We are using scalatest_2.9.2-1.8.jar.

It runs fine with the Junit testrunner, just a bit annoying to set it up everytime in stead of using a shortcut to start the ScalaTest testrunner. Any ideas how to fix this?

Cheers,
Alf
