os302-xo1 System fails when showing ogg file with Browse

[mikus]

os302-xo1 Launched Browse. Entered http://olpc.dailymotion.com/ as the URL. On the displayed webpage, clicked on the second-from-left image ('Un jour ... a Paris ...' - the one with Walter Bender's face). The file started to be shown, but the video froze immediately. The audio stopped quickly. X was completely frozen -- no input was accepted from green XO keyboard nor from USB keyboard nor from USB mouse. [Took system dump via ssh connection.] Had to reboot XO-1 to get X working again.

Could be same problem as #10252

os302-xo1 - system dump when X frozen from playing ogg file

[mikus]

FYI - from an earlier test, where the problem first showed up. This earlier test was with os302-xo1 enhanced with additional RPMs. Just in case these additions affected the problem, I repeated the test with a nearly-virgin os302-xo1. The data from the virgin-os302-xo1 test is what is attached above.

Running os303 with very latest (as of 8/3/10) RPMs applied. Now, with Browse, the "Un Jour ... a Paris" video on olpc.dailymotion.com correctly plays to completion.

Fresh install of os304, using same test video as above. XO-1.5, works fine. XO-1, works fine.
