[PD] special characters in GUI labels

[marius schebella]

hi,
I had to debug a patch this weekend, that included a brace/curly bracket 
'{' in a label for bng.
the problem with this was, that I had a hard time finding the error 
because pd just kept crashing/freezing.
I could not reproduce the error, since it was not possible to create a 
label name that included a '{', so I wonder if there are pd versions 
that allow this???
best,
marius.
