Bug#518034: audacity: Audacity crashes at startup with "Locking assertion failure"

[Stefan Monnier]

Package: audacity
Version: 1.3.6-3
Severity: important

I cannot start audacity any more.  It worked fine a year ago, and I haven't
used it since, so I'm not sure when the problem appeared.  I tried it on
all my Debian machines (tho they all run a pretty similar setup).

The error I get is the following:

1- I type "/usr/bin/audacity"
2- A window flashes (well: my window-manager asks me to place the window,
    but it disappears as soon as I place it).
3- I get the following message in the xterm from which I started the program:

% /usr/bin/audacity
The program 'audacity' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
  (Details: serial 8447 error_code 9 request_code 14 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
