#2567 \balloonGrobText does not work properly with slurs

The image shows what happens when \balloonGrobText is used with a slur.
Uncommenting the \override demonstrates a possible workaround. I tried
this code in 2.14.2 with the same result.

\version "2.15.39"

\new Voice \with { \consists "Balloon_engraver" }
\relative c'' {
% uncommenting the following line is a possible workaround
%\override BalloonTextItem #'X-extent = ##f
\balloonGrobText #'Slur #'(0 . 2) \markup { "I'm a slur!" }
c( d e f)
}

I don't think balloons were ever meant to go on spanners - is there a way this can be indicated in the docs? I'm pretty sure that what's happening is that balloons are triggering slur position calculations before horizontal spacing is finished, which causes a weird slur to be printed.

I changed the label to type-crash because with 2.17.25 up to 2.17.28 the initial code returns a segfault.

Here are some more examples for Stem and Beam:

%% tested with all major- and some devel-versions from
\version "2.12.3"
%% up to
\version "2.17.28"

%% Only for better viewing:
\layout {
  \context {
    \Voice
    \override Beam #'color = #red
    \override Beam #'layer = #5
  }
}

%%%% balloonGrobText for Stem under Beam

%%%% Same for automatic/manual Beams
\new Voice  \with { \consists "Balloon_engraver" }
  \relative c'' {
    %% 2.12.3, 2.14.2: ok
    %% 2.16.2, 2.17.28: text and balloon is printed, no real Beam
    %% Note the very small displaced Beam
    \balloonGrobText #'Stem #'(3 . 3) \markup { "Stem" }
    a8 a a a
  }

%%%% balloonGrobText for Beam

%%%% Automatic Beams
%% 2.12.3, 2.14.2, 2.16.2, 2.17.28: Beam is printed, no text or balloon
\new Voice  \with { \consists "Balloon_engraver" }
  \relative c'' {
    \balloonGrobText #'Beam #'(3 . 3) \markup { "Beam" }
    a8 a a a
  }

%%%% Manual Beams
%% 2.12.3: ok
%% 2.14.2, 2.16.2: text and balloon is printed, no real Beam
%% 2.17.25/26/27/28: Segfault
\new Voice  \with { \consists "Balloon_engraver" }
  \relative c'' {
    \balloonGrobText #'Beam #'(3 . 3) \markup { "Beam" }
    a8[ a a a]
  }
