Unfortunatly nothing is fixed, all the symptoms mentioned above are still there, tested with hrev:50608.
hrev50609 still does not show the icons or screenshots.
Not reproducible in any way for me, a lot changed in the meantime. In case someone can reproduce it just let me know.
The media_server is now in good shape, I consider this ticket closed.
That feature is implemented as result of my contract, for more informations :
Ticket can be now closed.
Should be fixed in hrev50603.
