What version of Org are you using?

I haven't had any luck reproducing this.  Isolating the error with a
minimal configuration and minimal Org file would be very helpful.

At some point, maxwidth is being set very low (-4 here).  Try to see
where this happens.  For example, what value for width does
helm-get-org-candidates-in-file send into org-format-outline-path?  If
that seems to be appropriate, debug org-format-outline-path and see when
it's getting set to the low value.
