I'll send you a possible fix but it needs a bit of testing. It has to do with (probably spurious) spaces which means that the parbuilder then considers the dir node to be a reasoable breakpoint (well, kin dof okay as one gets what one asks for), but I'll be a bit more agressive in dealing with that.

Thank you, Hans, for looking into this so soon.

I did try what you sent, but see no difference. I have eliminated the changes to spaceskip as a cause and simplified the example, removing the spaceskip and delimitedtext.

New example, in which I get a spurious line after the third and fourth Walt Kelly entries:

   %% Demonstration of spurious line insertion on full paragraph with bidi

   \setupdirections     [bidi=on,method=unicode]

   \enabletrackers      [typesetters.directions]
   %\showmakeup          [glue,dir]

   \setuppapersize      [Testing]

   \setuplayout         [width=fit,
                          backspace=1.4in,
                          cutspace=1in,
                          leftmargin=0.65in,
                          rightmargin=0.65in]
