Usbmount only mounting two partitions #44

Hi,

If I plug my usb harddrive, which has 3 ntfs partitions (sdd1, sdd2 and sdd4) on it in a usb port usbmount starts mounting. It mounts /dev/sdd1 and /dev/sdd2 or sometimes /dev/sdd1 and /dev/sdd4 and than stops.So it seems to only mount two partitions... Weird!
Have checked usbmount.conf and udev rules, but not found the problem.
I'm running debian squeeze (old 32 bit armel) on a device, which I cannot update the kernel on.
usbmount v.0.0.22, fuse and ntfs-3g are installed!
Any ideas ?
