multiple fret-diagram-x markup commands and lilypond-book safe-mode

[Julien Rioux]

Hi,

I've found a strange behaviour using lilypond-book --safe on a lytex 
file: With multiple snippets each containing one \fret-diagram-x markup 
command, compilation works for the first snippet but fails on the next 
one. Then if you run lilypond-book --safe a second time, it will 
successfully compile the second snippet but fail on the third, etc.

I attach a minimal example file and the log of the error on first run of 
lilypond-book --safe. The same file compiles perfectly without the 
--safe switch. I am assuming that \fret-diagram-x markup commands are 
allowed in safe mode. Minimal trials with lilypond -dsafe have led me to 
believe that this should work.

Thanks and regards,
Julien
