gvfsd-mtp crashed with SIGSEGV in ptp_transaction_new() (when plugging in android phone via USB port)

[Cavsfan]

On Saucy: I got this error when I plugged in my andriod phone into a USB port.
It gave a different error message but is the exact same problem that happened when I did it before and this bug was filed:

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
