 My backend is running on a banana pi, I'm using the compiled myth packages
 from deb-multimedia.org:
 deb http://www.deb-multimedia.org jessie main non-free
 deb http://www.deb-multimedia.org jessie-backports main

 mythtv-backend and related packages all have the version 0.28-dmo6~bpo8+2

 I encountered this crash after upgrading from 0.27 to 0.28 in a script I
 use which exports shows as a video and then deletes the original program,
 since Recorded.delete() calls Recorded.getProgram(). But, you can
 essentially simplify this down to the following, which will fail for any
 recording where a bookmark has not been set.
 {{{
 #!python
 db = MythDB()
 rec = Recorded((chanid, starttime), db=db)
 rec.getProgram()
 }}}

 I get the following error message:
 {{{
   File "/etc/mythtv/mythvidexport.py", line 71, in __init__
     self.rec.getProgram()

 }}}

 As of MYTH_PROTO_VERSION 88, bookmarkupdate is the last item in the
 response to QUERY_RECORDING TIMESLOT. For some reason, this is always
 '4294967295' (0xffffffff) for any recordings without bookmarks on my
 setup, despite the fact that the bookmarkupdate column is 0 for these
 programs in the database.

 Is there any logging that I can enable in mythbackend to find the cause? I
 did a quick check of the libmyth source code but I didn't see anything
 suspicious.
