Comment(by yan at seiner.com):

 I don't think this has to do with Qt widgets.  I can get a fairly reliable
 segfault on channel 17 in the early morning, but in the evening I can scan
 most channels.  I suspect it has to do with signal strength and/or
 interference.

 Also, I've rebuilt both front and backends and the backend will segfault
 on channel changes.  I don't have time to do a full trace (I'm leaving
 town in a couple of hours), but here's the tail end of mythbackend.log:

 Channel #4 nam<C4>?) 0-0 mod([Reserved]) cTSID(0x0)
  pnum(0) ETM_loc(0) access_ctrl(0) hidden(0) hide_guide(0)
 service_type(32) source_id(35191)

 Channel #5 name(<F0>? ) 0-0 mod([Reserved]) cTSID(0x0)
  pnum(0) ETM_loc(0) access_ctrl(0) hidden(0) hide_guide(0)
 service_type(32) source_id(36727)

 Channel #6 name(0?) 0-0 mod([Reserved]) cTSID(0xa)
  pnum(0) ETM_loc(0) access_ctrl(0) hidden(0) hide_guide(0) service_type(6)
 source_id(28527)
  descriptors length(32) count(1)
   Data Broadcast Identifier Descriptor (0x66) length(111)

 Channel #7 name(??<F0>?) 0-0 mod([Reserved]) cTSID(0x0)
  pnum(0) ETM_loc(0) access_ctrl(0) hidden(0) hide_guide(0) service_type(0)
 source_id(0)

 Channel #8 name(^D^Dw?) 776-103 mod(UNKNOWN 105) cTSID(0x0)
  pnum(0) ETM_loc(0) access_ctrl(0) hidden(0) hide_guide(0)
 service_type(48) source_id(35703)

 Channel #9 name(X??? ) 0-0 mod([Reserved]) cTSID(0x0)
  pnum(0) ETM_loc(0) access_ctrl(0) hidden(0) hide_guide(0) service_type(0)
 source_id(36215)

 At this point the backend went away.

 I was attempting to change channels on liveTV with the frontend.
