I'm using current stable on Ubuntu 15.10.

Steps to reproduce:
 - open emacs gdb-many-windows mode (I only hit this bug if the registers
buffer is open)
 - set a breakpoint
 - run

The following text appears in the gud window:
(gdb) Python Exception <class 'NameError'> name 'long' is not defined:
Python Exception <class 'NameError'> name 'long' is not defined:
Python Exception <class 'NameError'> name 'long' is not defined:
Python Exception <class 'NameError'> name 'long' is not defined:

Hitting enter reruns the program from the beginning.
