reassign 762571 libvorbisfile3
thanks
Thanks for the bug report! I reproduced the problem in several versions
of Debian and Ubuntu.
However, the problem isn't in audacity, but in libvorbis. The file
importer calls libvorbis' function "ov_pcm_seek" with seek position 0 in
order to start reading at a well-defined position. But libvorbis seems
to have problems with seeking to 0 in certain files.
This is a known problem in libvorbis and has been fixed in r19159 of
their trunk 3 months ago:
https://trac.xiph.org/changeset/19159
https://trac.xiph.org/ticket/1486
Maybe the changeset can be backported to the libvorbis versions
currently in the repositories? Backporting it is trivial, at least to
the packages of libvorbis-1.3.2 the patch applies without modifications
(using only fuzz). I just tried it and indeed it fixed the problem with
audacity.
Cheers,
Martin

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:

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.
