> Do you have a way to reproduce the issue with more likelyhood ?

No, There are no definite steps to reproduce it. But lete me explain my setup.
this may help in understanding the issue. I was testing hlsdemux on N9 platform
(MeeGo) with webkit. The platform had a resource management system working. I
was playing hls stream then moving the browser to background and foreground,
when i expereienced this issue. 

In the code itself, gst_hls_demux_stop_update is always called after
gst_hls_demux_stop_fetcher except in this particular case. I also verified with
backtrace that fetcher thread is indeed blocking the update thread. If this
patch, i did not experience any deadlock.
