[Bug 705077] Re: mythbackend will segfault about 10 minutes after starting. "segfault at 50 ip 0209d2dc sp bff215c0 error 4 in libQtCore.so.4.7.0[2041000+290000]"

 

Hi Will,  thanks for the bug report, but there's a few things missing
here.

Can you please follow the directions here:
http://www.mythtv.org/wiki/Debugging#Debugging_with_Ubuntu_packages

Particularly
1) En the apport service
2) Install mythtv-dbg
3) File the crash as it occurs so it will include a backtrace.  Apport should intercept the crash for you.

Thanks!

Title:
  mythbackend will segfault about 10 minutes after starting. "segfault
  at 50 ip 0209d2dc sp bff215c0 error 4 in
  libQtCore.so.4.7.0[2041000+290000]"

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Invalid

Bug description:
  After performing an apt-get update && apt-get upgrade today (1/19),
  mythbackend is no longer stable. There is no exiting information
  contained in the mythbackend.log file, however there are numerous
  reports of "MainServer, Warning: Unknown socket closing MythSocket"
  and "MainServer, Error: Failed t oopen master server socket, timeout."
  The segfault is recorded in /var/log/messages as follows: "kernel:
  [10921.030926] mythbackend[5755]: segfault at 50 ip 0209d2dc sp
  bff215c0 error 4 in libQtCore.so.4.7.0[2041000+290000]"

  This issue was not present in the earlier package, which I updated to
  earlier this week when I upgraded from 10.04 to 10.10.
