#7034: mythbackend crashed with SIGSEGV in free()

 Reporter:  mrand at pobox.com   |       Owner:  ijr       
     Type:  defect            |      Status:  new       
 Priority:  minor             |   Milestone:  unknown   
Component:  MythTV - General  |     Version:  0.21-fixes
 Severity:  medium            |     Mlocked:  0         
------------------------------+---------------------------------------------
 Since the expiration code has changed so very little since then,
 submitting even though this is 0.21 and QT3.  Feel free to close if it is
 not worth pursuing or if you believe it to be somehow fixed by QT4.
