+					LibParted, a backend library &partman; uses, has problems with systems where the Linux Device Mapper is used in a way it doesn't understand. Unfortunately it reacts to some of these situations with segmentation faults, i.e. crashes. &partman; therefore tries to avoid these situations by using alternative backends. If it cannot do that, however, and has to rely on LibParted, it will print a message like the one mentioned and nevertheless try its best.
