Public bug reported:

Binary package hint: rhythmbox

Using the beta of 9.10 and I had a Kernel Panic the other day.  I have
these periodically and usually happen because of one of two things or a
combination of the two--I don't know if there are two seperate problems
or if it is the same.  The two things that seem to cause the kernel
panics are me being connected to my wireless network at school which
uses WPA2 Enterprise security with AES encryption, and/or rhythmbox is
running and playing music.  These problems also occurred on my main
install of 9.04.

Various things happen when it freezes up including, the computer freezes
but I can still use the mouse, completely freezes can't move mouse,
music goes into a loop, and/or the caps/num lock lights begin flashing.
Something that happened on the Beta which has never happened before is
that apport actually detected one Kernel panic as it was happening, and
asked me to report it.  I tried doing this but it would just hold at the
collecting information stage and apport would pop up again saying there
was another panic.

I am filing this bug under Rhythmbox because for the first time after a
recent panic there seemed to actually be a trace of it in the log files
(usually there is nothing).  The logs files made it look as if Rhythmbox
might be the culprit.  Here they are for your analysis (including the
previous event to the suspicious events and the first event of the
restart):

Because the panics are all so hard that things rarely make it into the log 
files so it is hard for me to gather information, but I will try to provide any 
addition information requested!  Thanks!

PS -- apport does not appear to work for me when I try to access it from
the Applications:Systems menu,  I don't know if this is normal or if I
should file a bug against it.
