New plug-in 1.3 - open project: NoSuchMethodError: sbt.ModuleReport.<init>

Hi,

just updated to CE 14.0.3 and Scala Plug-In 1.3. This is what I get when I open a project:

Error:Error while importing SBT project:

See complete log in /tmp/sbt0.log

(That log file doesn't exit). Should I be worried?
