 Severity:  medium                     |  
---------------------------------------+------------------------------------
 Mostly I got core dump when leaving playback. Now I updated to [8736] and
 hoped that #1047 fixed this problem but right now I got core dump again.
 This time when leaving from delete recordings menu but looks like this is
 the same problem.

 Here is log output:
