It is in SSDPCache::RemoveStale() the keys are added in the first pass to
lstKeys, an Unlock() is done, then the keys in lstKeys are Release()d and
m_cache.remove()d. Most of the Lock()/Release() calls there could also
benefit from a simple QMutexLocker.

I've yet to see a crash after the fix (that wasn't related to me trying to
output too late).
