Probably the same issue:
no_label, and yes_label arguments of yesno cause
File "/usr/lib/pymodules/python2.7/dialog.py", line 1571, in yesno
**kwargs)[0]
File "/usr/lib/pymodules/python2.7/dialog.py", line 825, in _perform
child_rfd)
File "/usr/lib/pymodules/python2.7/dialog.py", line 765, in
_wait_for_program_termination
"perhaps the dialog-like program could not be executed; "
dialog.PythonDialogErrorBeforeExecInChildProcess:
<PythonDialogErrorBeforeExecInChildProcess: perhaps the dialog-like program
could not be executed; perhaps the system is out of memory; perhaps the maximum
number of open file descriptors has been reached>
Workaround:
Replaced python-dialog 2.7 with 2.11 from
