Bug#762571: audacity: Hang when asked to open Ogg Theora file

[Petter Reinholdtsen]

Package: audacity
Version: 2.0.1-1

Hi.  I discovered this issue in Jessie (version 2.0.5-2), but it is also
present in Wheezy.  In the KDE file manager, any Ogg Theora video file
is passed to audacity by default (see bug #762561 for that story), and
the audacity program just hang after showing two empty windows.

I tried to install the audacity-dbg package and triggering this hang in
gdb to get a backtrace:

(gdb) 

The issue should be fairly easy to reproduce.  If you need a Ogg Theora
file, the gtk-recordmydesktop package can create one for you.  It would
be better if audacity loaded the audio of the Ogg Theora file instead of
just hanging.
