I cannot reproduce this.  Please show the exact sequence of commands
you used, including the program which you ran under the debugger, for
me to be sure I did the same.

Also, what is your GDB version?

IME, Python exceptions in GDB usually mean your Python support files
are from a different GDB version, so perhaps double-check your GDB
installation.

Thanks.
