segfault in input/regression/accidental-suggestions.ly

[Reinhold Kainhofer]

I'm always getting a segfault trying to run "make doc". In particular, the 
input/regression/accidental-suggestions.ly regression test fails...

Here's the output of valgrind to help track down the problem:

The problem appeas only when 
     \set suggestAccidentals = ##t
is used...
