Comment 3 for bug 1228553

I can confirm that this bug is present for me in a fully updated Luna environment.
If I scroll around, select to play a song, then select another after 2-3 songs it will crash.
Running Noise with --gst-debug-level=2 I get this output:
john@Paradise:~$ noise --gst-debug-level=2

[_LOG_LEVEL_WARN 08:23:38.186964] [Gdk] The program 'noise' received an X Window System error.This probably reflects a bug in the program.The error was 'BadLength (poly request too large or internal Xlib length erro'. (Details: serial 5660 error_code 16 request_code 98 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 GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

It's causing Noise to crash consistently, rendering it useless.
