What happened in Napoli during the Hitler's visit (may 1938) ?

Hi,

Flippo Anfuso tells in his memoirs that the "only bombing" committed in Napoli hurted the ethiopian female singer who sang Aida in the opera.
He tells also that Hitler asked twice about her health, showing respect to her rank of ethiopian princess.

Anfuso says that a beam fell and wounded the singer.

What happened exactly ? Was it an accident ?
Do we know more about it ?

Who was this ethiopian princess singer ?

AFAIK it was an accident.
