Build Identifier: I20100312-1448 (3.6 Milestone)

I cannot run FindBugs on some of my Eclipse projects. I get the following exception:

java.lang.IllegalArgumentException: Attempted to beginRule: MultiRule[P/MyProject,P/.org.eclipse.jdt.core.external.folders], does not match outer scope rule: MutexSchedulingRule, project: P/MyProject

Reproducible: Always

Steps to Reproduce:
1. Right-click on a project
2. Select FindBugs -> FindBugs (version is 1.3.9, but it never seems to actually get to the FindBugs code)

This does not hold for ALL projects, just for some. I'm not sure what's happening in the code though, so I can't tell what's different about the projects.
