#3269: mythwelcome freeze hard lock

 Reporter:  anonymous  |       Owner:  ijr    
     Type:  defect     |      Status:  new    
 Priority:  minor      |   Milestone:  unknown
Component:  mythtv     |     Version:  0.20   
 Severity:  medium     |

 It is really hard to describe this bug: at random my computer freezes (a
 real hard lock, i have to shut it down pushing the power button for 5
 seconds - no ssh, no pings) when mythwelcome is running. Everything runns
 fine when mythfrontend is in foreground, but not with mythwelcome. The
 freeze happens at random: sometimes it works for hours and then the
 computer shuts down cleanly with mythshutdown when the recording stops,
 and sometimes (about 90% of the time) the computer hard locks in the
 middle of a recording or before shutdown. There is nothing in the logs
 that would help me, and I am really lost about how to debug this problem.

 This is on Ubuntu 6.10 with mythtv svn revision 13150 (but it happens with
 -fixes too, I updated in the hope the bug gets away, but no luck).
 kernel 2.6.17-11 with ubuntu patches.

 The freeze happens only with mythwelcome, so I suppose it is really a
 mythwelcome bug.

 Thanks,
 Simon
