It's even worse: It does not depend on parallel or multiple voices or so. The 
problem happens as soon as the text cresc spanner starts at a skip. Minimal 
example:

\version "2.11.39"
\relative c' {   \setTextCresc s2\< g2\!   }


A little digging in the line-spanner.cc code (and adding debug output) shows 
that in Line_spanner::calc_bound_info, the "X" value is really set to nan 
(i.e. bound_grob->extent (commonx, X_AXIS).linear_combination (attach)) 
returns "nan"). If I use g2\< instead of s2\<, a value of 17,... is returned.

Cheers,
Reinhold
