MC doesn't open files with external editor

[ilson]

1. Run mc.
2. Press F9, navigate to "Options -> Configuration...", uncheck "Use internal edit" and press Enter.
3. Execute EDITOR=vim (or specify any other editor command).
4. Select a file and press F4. MC window flickers for an instant and nothing else seems to happen. FWIW, if I press and hold F4, I get this in console:

   ^[OS^[OS^[OS^[OS^[OS^[OS^[OS
