Comment 1 Pino Toscano 2011-07-03 21:48:41 UTC 
Try using a phonon backend different than gstreamer.
Comment 2 Gabriel 2011-07-03 23:35:52 UTC 
OK! Okular now works fine. Many thanks!
Comment 3 Myriam Schweingruber 2011-07-04 18:38:33 UTC 
This seems to be a problem with libgstreamer, not much we can do about, sorry.
