One of our customers is having an issue when loading up an Iteration Plan in the Eclipse client.  The Plan loads fine in the web client.  The NullPointer that is returned is listed below and it references:

Caused by: java.lang.NullPointerException
    at com.ibm.team.apt.internal.common.time.TimespanIterator.<init>(TimespanIterator.java:59)
    at com.ibm.team.apt.internal.common.WorktimeScheduler.calcutateWorkingTime(WorktimeScheduler.java:117)

What's the best way to debug this issue? I looked in the server logs but just saw the same error.  I looked at all the work item changes that occurred around the time it first occurred and it was mostly updating the Time Spent.  

Customer is on RTC 3.0.1.3.
