Adding a conflict is certainly not the way I want it to go, as dk-disks is meant
to work with dm devices.

Where exactly in the rules does it overwrite data setup by device mapper?
Which part exactly in the rules file does break other apps?
What do you suggest instead?

FWIW, this is the relevant part of the current (devicekit-disk 004-1) rules file:

##############################################################################################################

# pick up device-mapper data; this really should be done by rules installed
# by the device-mapper package

KERNEL!="dm-*", GOTO="device_mapper_end"
ACTION!="add|change", GOTO="device_mapper_end"

IMPORT{program}="devkit-disks-dm-export %M %m"
ENV{DKD_DM_NAME}!="?*", GOTO="device_mapper_end"

SYMLINK+="disk/by-id/dm-name-$env{DKD_DM_NAME}"
ENV{DKD_DM_UUID}=="?*", SYMLINK+="disk/by-id/dm-uuid-$env{DKD_DM_UUID}"

The next upload of dk-disks (devicekit-disk 007-1) will contain
