comparison data/fileio/MP3FileReader.cpp @ 348:edda24bb85fc

* Skip ID3 block when reading MP3 files (so long as ID3 support is included)
* Show progress when retrieving audio file from playlist
* Avoid -- but do not actually fix -- segmentation fault on exit.  I am
  totally stumped at the moment about why both the PA and JACK audio targets
  should crash when properly shut down.  For the moment, we just don't shut
  them down...
* Fix incorrect behaviour (introduced on Friday as part of a different fix)
  when replacing main model in situation where no current main model exists
