maybe its the same problem?
excerpt from my /etc/udev/udev.rules:

# device mapper creates its own device nodes, so ignore these
#lge: see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=343671
#KERNEL=="dm-[0-9]*",           NAME=""
KERNEL=="dm-[0-9]*",            OPTIONS+="ignore_device"
KERNEL=="device-mapper",        NAME="mapper/control"
