Comment (by Andy Stevenson <lists@…>):

 I'm using SchedulesDirect in the US, for which I believe mythfilldatabase
 uses wget (streaming to stdout).

 Here's a dump from my console the night I was working on this.
 - Normally it would hang at the end of the transfer, right before printing
 this line:
 {{{
 2010-09-18 00:48:33 (38.9 KB/s) - `-' saved [324228]
 }}}
 - I built everything debug and then stopped in the debugger... at the
 point that it was hung, the number of bytes read was equal to the filesize
 in bytes (in util.cpp), but the Qt reader kept returning errno==EINTR and
 never coming back.
