I think it depends on how the petrification affects the magical properties of your gear. GM being nice, it's petrified along with you and the rest of your stuff, no affect. GM decides to be an ass or decides he wants to get rid of your character and the magic items in question has them interact and cause mayhem and chaos.
imagine it though.
Normally, the character's gear is petrified along with the character and renedered inert.
I have to add the breaking the character's arms off will make it much more difficult to return the character to a playable condition.
Nothing Mending wont fix
