(apologies if udev rules bugs should be filed somewhere else, #gnome-os suggested using systemd's bugtracker) Fedora-19's 69-libmtp.rules file makes the system use MTP for my old Philips Vibe Mp3 player. Unfortunately MTP does not really work with this device, so I fixed making a copy of that rule file in /etc/udev/rules.d and commenting out this line in the copied file: #ATTR{idVendor}=="0471", ATTR{idProduct}=="207b", SYMLINK+="libmtp-%k", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1" In this way the file gets mounted as a plain USB storage and things work. Note that when connecting the device, it let's you switch between the two modes (MTP and mass storage), so ideally if udev could apply a different rule depending on the choice it would be perfect. Right now it always use MTP and that never works even if you actually pick MTP on the device (this may be a gvfs-mtp bug though).
This should be taken to libmtp as they ship the rules file.
