Public bug reported:

Binary package hint: audacity

In Hardy, when I try to save a project or export a file in Audacity
(1.3.4-1.1ubuntu1), I get a file dialog with somewhat abridged content
(empty where the file listing should be, no directory selector header,
etc) and my CPU jumps to 100% of one core.  It appears that Xorg
(1:7.3+10ubuntu10.2) is the process eating the CPU, rather than Audacity
itself.

Steps to reproduce (some of which may not be strictly necessary but this
is what I did):

1. Open Audacity, navigate to the Preferences dialog and turn off the "play 
while recording" checkbox.
2. Open a mixer such as kmix and set your capture options as needed to record a 
known sound source.
3. Use Audacity to record about 4 minutes from your chosen source.
4. Trim a couple of seconds off each end of the recording.
5. Click on File -> Export... Change the filetype to OGG and change the 
"Options" to set the quality to 10.
6. Try to navigate to the "Filesystem" via the link on the left of the dialog.

Somewhere around step 5 is when I noticed my CPU being rather heavy.
By that point, my pointer had changed to the "busy-wait" spinning icon.
I can enter a (path and) filename at the top, but clicking "Save" does
nothing.  If I hit Escape at this point, the dialog closes, but the CPU
remains pegged at 100% of the one core.   It stays there until I kill
Audacity (though I didn't try to "close" it, I got frustrated and killed
it from the command line).

What should happen:

The program should default to the user's home directory, and let me
enter my details and save the file or project out. :-)
