This call stack indicates that, after performing a "country lookup" request, an attempt to free the data describing the request resulted in an error. In investigating several dumps (see the related Mantis issues) the dumps indicate that either the memory was freed twice, or the memory should never have been freed (eg, it was allocated on the stack).

The CountryLookup request can only be enqueued from a couple of places. One is meant to block; the other is meant to "fire and forget" the result. A blocking thread is not apparent in any of the dumps. But the calling code appears to be correct in both cases, so the problem must indicate that synchronization isn't working as intended.
