please can you explain how to debug the wheezy problem

It seems like it's waiting for the password prompt, due to the format of the prompt not matching what we're expecting. Could you execute the command via su on the system and report back what the password prompt is? We can open an issue for this as well and get the regex updated so it will match the password prompt going forward.

Ok the command via su on Lenny

seidenberg@backupPC:~$ su root -c /bin/bash -c echo SUDO-SUCCESS-piguunfptuenxfyxauqmavtunfzjnayk; LC_CTYPE=C LANG=C /usr/bin/python /home/seidenberg/.ansible/tmp/ansible-tmp-1403175187.6-175350529956768/command

and the command on wheezy

seidenberg@seidenberg1:~$ su root -c /bin/bash -c echo SUDO-SUCCESS-piguunfptuenxfyxauqmavtunfzjnayk; LC_CTYPE=C LANG=C /usr/bin/python /home/seidenberg/.ansible/tmp/ansible-tmp-1403175187.6-175350529956768/command

Interesting, no obvious difference there.
