I *think* I've found a kind of bug..
I was tryin' to suppress a couple of bars in a StaffGroup (made of one
Staff and one TabStaff), using \stopStaff
I've found out, after several tries (see attached file), that the
problem arises when I use \stopStaff \startStaff in a score which has
a TabStaff included in a StaffGroup.
In all the other cases it works fine.
The error message links to a line in tablature.scm
Please review the file and tell me if I've done something wrong or if
that could be some kind of bug.
Thanks!
Federico
