Ties go a bit haywire, bug?

[Wilbert Berendsen]

Hi,

in 2.11.26 when there are many ties, some have positioning errors. 2.10 has no 
problems, but for many other improvements I'm already dependent on 2.11.x :)

This is an excerpt, attached a PNG which shows that some ties are drawn too 
long. Must I report this as a bug?

\version "2.11.26"
rh = {
%       \repeat unfold 10 { a'1~ | }
        \repeat unfold 4 { <a' c''>1~ }
        \repeat unfold 2 { <c' a' c''>1~ }
        \repeat unfold 2 { <c' a' c'' d''>1~ }
        \repeat unfold 2 { <c' f' a' c'' d''>1~ }
        <c' f' a' c'' d''>8\fermata r4 r4. r4 \bar "|."
}
\score {
        \new Staff = "rh" \rh
}

With best regards,
Wilbert Berendsen

PS: I'm really impressed with all the improvements in the latest releases, 
thanks!
