_curses.error: cbreak() returned ERR when using --sync or --save or --resume together

[PlasmaHH]

Whenever I use more than one of the mentioned flags I get the following error:

Traceback (most recent call last): File "./sifter.py", line 842, in main() File "./sifter.py", line 833, in main gui = Gui(ts, injector, tests, args.tick) File "./sifter.py", line 369, in init curses.cbreak() _curses.error: cbreak() returned ERR

This does not go away by setting their xterm256 TERM environment variable

This is especially unfortunate for the case of trying to use --sync and --resume
