Comment (by paulh):
Made a little progress on this.
I can randomly reproduce it now using a VBox as source by starting and
stopping live TV and switching channels a few times it will eventually
segfault.
Using gdb to look at a few things the only strange thing I see is m_buffer
instead of being filled with the stream data it contains a web page
showing a "500 Internal Error". So for whatever reason the VBox is failing
to start streaming and that is somehow causing the segfault.
I suspect it has something to do with the QEventLoop in
HTTPReader::DownloadStream(const QUrl url) exiting quicker than when a
stream succeeds possibly with the order of the SIGNALS being called in a
different order but I still can't see how that leads to the segfault in
the BT. Open to suggestions :)
