During workspace cleanup, we are getting a null pointer exception in our logs:

INFO: Started Workspace clean-up
Exception in thread "Workspace clean-up thread" java.lang.NullPointerException
at hudson.plugins.clearcase.AbstractClearCaseScm.processWorkspaceBeforeDeletion(AbstractClearCaseScm.java:509)
at hudson.model.WorkspaceCleanupThread.shouldBeDeleted(WorkspaceCleanupThread.java:124)

at hudson.model.AsyncPeriodicWork$1.run(AsyncPeriodicWork.java:54)
at java.lang.Thread.run(Thread.java:619)

We use the standard view name in clearcase as hudson_${NODE_NAME}_${JOB_NAME} which may be causing the issue, I'm not sure. We also only use the base clearcase support and we use slave agents, though we tie each job to only one agent.
