gtkpod

Similar to previously reported. Part of many attempts to export.
iPhone 4 if that matters.
The program 'gtkpod' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
(Details: serial 448743 error_code 161 request_code 149 minor_code 7)
(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.)

Program exited with code 01.

I'm not sure how to debug, but since I have sources you could tell me where to slap in debug code and breakpoints.
