Bug#814813: spurious output to stderr

[Daniel Pocock]

Package: flactag
Severity: important

When starting up and also after pressing the 'W' key to write, flactag
is sending a whole lot of errors to stderr.  From comments in the
discussion forums it looks like they may be originating from libmusicbrainz

When the errors appear after displaying the UI, they corrupt the UI, it
is no longer possible to see the list of keystrokes at the bottom of the
screen.  Pressing 'Q' exits the application though.

- what is the impact of ignoring these elements?  Should flactag just
ignore them (or have a command line switch to ignore them) without
printing errors?

- could the errors be shown in the UI?  Maybe libmusicbrainz needs to
support some logging framework and the UI could then intercept log
messages to display them cleanly
