Comment 26 for bug 1068921

I set a breakpoint in nsMsgDBFolder::EndNewOfflineMessage() to trigger when this condition occurs, and I made a note of various local variables when it happens (hopefully it will be useful):

Main thread:
tellPos = 4450254
messageOffset = 4271281
curStorePos = 178973
m_offlineHeader->GetMessageSize() returns 1778
m_bytesAddedToLocalMsg = 83
m_numOfflineMsgLines = 2447

On the IMAP thread (in nsImapProtocol::NormalMessageEndDownload()):
m_bytesToChannel = 178890
m_parser.fSizeOfMostRecentMessage = 178890
