Bug in tablature's 6th string

[Yannick KIRSCHHOFFER]

Hi,

When typesetting guitar tablatures, lilypond drops all notes on the 6th string:

---------------------------------------

\version "2.10.0"

\score {
        \context TabStaff {
                e,4 a, d g b e' r2 |
        }

        \layout { }
}

---------------------------------------

GNU LilyPond 2.10.25
Processing `bug.ly'
Parsing...
Interpreting music... 
bug.ly:5:16: warning: could not calculate a string number.

                e,4 a, d g b e' r2 |
[2]
Preprocessing graphical objects...
Layout output to `bug.ps'...
Converting to `bug.pdf'...

---------------------------------------

I get these on all my ly files which were still working with 2.10.10 I think.

Thanks if someone could fix this.
