Error in DeferredResource handler

[jedimstr]

Every once in awhile I received this large error block. It recovers and continues to work without crashing afterwards, but it is a bit disconcerting.

I originally opened up this issue in the main P2Pool repository, but was told this was an issue with the ExtendedFrontEnd not being up to date with the latest commits from P2Pool:
