This problem is reproducible, at least as of a build from fresh CVS code, June 28th. Start mozilla with the about:blank page as command-line URL. Close mozilla clickin in the window manager´s close window button. (obviously, setting up XPCOM refcnt balancer and bloat logs) I isolated down to the about:blank page this bug from other test case. I haven´t been able to track exactly where the problem happens, but if I manually release those five references, I get rid of all the leaks caused by it, namely: [CLASSNAME NUMBER-OF-INSTANCES-FREED] GIFDecoder -1 ImageConsumer -1 ImageNetContextImpl -1 ImageRendererImpl -1 ImageURLImpl -1 ImgDCallbk -1 NetReaderImpl -1 nsAsyncStreamListener -1 nsAsyncStreamObserver -1 nsDocLoaderImpl -1 nsDocumentOpenInfo -1 nsEventQueueImpl -1 nsEventQueueServiceImpl -1 nsFileChannel -1 nsFileTransport -1 nsHashKey -11 nsHashtable -2 nsImageGTK -1 nsLoadGroup -1 nsLocalFile -1 nsMemoryImpl -1 nsNoAuthURLParser -1 nsPipe -1 nsProxyEventClass -2 nsProxyEventObject -2 nsProxyObject -2 nsResChannel -1 nsResProtocolHandler -1 nsStdURL -11 nsStdURLParser -1 nsStr 3 nsStringKey -10 nsSupportsArray -10 nsSystemPrincipal -1 nsVoidArray -10 xptiInterfaceInfo -2 which leaves the bloat log for the about blank page to list only 8 classes, of them most are ghost leaks, but I still have to check them. I´m starting to consider this could be a circular reference problem, but I could not find a place to start. If I manually released one of the leaking nsFileTransport objects, I´d get -4 references on the leaking nsFileChannel, but also when releasing nsFileChannel I get nsFileTransport released, so that doesn´t look like the way to go. In any case, it is just too confusing for me. The refcnt balancer trees show the problems start when calling IL_GetImage(). there we setup the load operation, which gives us 6 references. One is released from the nsLoadGroup impl, but we still 5 which are interrelated and I cannot find where is the failure point. I´m guessing that the problem could be not releasing on image load finish, but again,, I am not able to find it. NEED SOME HELP PLZ! :)

I saw this happen a few builds ago, but have not been able to recreate it in the past week, including the most current build.
