It may be difficult to write such a small .ly input : I have experienced
this issue often appears when there are several staffs and enough bars.

For some scores, a possible workaround is setting the key signature
width large enough :

\override Score.KeySignature #'minimum-X-extent = #'(-0.8 . 1)

Put this line in the first "\new Staff{}" block for example, and play
with the second number until you no longer see any "adding reverse
spring".

If there is no key signature in the score, it may also work with the
clef instead, but I haven't tried.

Be careful that this workaround sometimes doesn't work, but thanks to
the great developers' work ;-), the problem seems to have been fixed in
the 2.7.x series.
