Crashed while shutting down to upgrade Lightning to latest snapshot.
The stack is small and just looks bad :
0 thunderbird.exe nsImapMailFolder::ParseAdoptedMsgLine mailnews/imap/src/nsImapMailFolder.cpp:4409
1 xpcom_core.dll NS_InvokeByIndex_P xpcom/reflect/xptcall/src/md/win32/xptcinvoke.cpp:101
2 nspr4.dll PR_Unlock nsprpub/pr/src/threads/combined/prulock.c:347
3 xpcom_core.dll nsProxyObjectCallInfo::Run xpcom/proxy/src/nsProxyEvent.cpp:181
4 xpcom_core.dll nsThread::ProcessNextEvent xpcom/threads/nsThread.cpp:521
Possibly a regression because it first appears 20091001032040 build.
It's even possible it's gone - because crash was happening steadily with every daily build until last crash with build 20091009032155 on 2009-10-12 00:00 - suddenly stopped

depending on how far we are into shutdown, we may not be able to get the message header, so we should really check the rv.
I suspect this has to do with receiving imap headers at shutdown time
fix checked in, a=me, since it's a top crash.
last build we see crash is 2009101500
