Buildroot fails with: mkusers: user already exists with group 'nogroup'

PATH="/home/user/buildroot/output/host/bin:/home/user/buildroot/output/host/sbin:/home/user/buildroot/output/host/usr/bin:/home/user/buildroot/output/host/usr/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games" /home/user/buildroot/support/scripts/mkusers /home/user/buildroot/output/build/_users_table.txt /home/user/buildroot/output/target >> /home/user/buildroot/output/build/_fakeroot.fs
mkusers: user already exists with group 'nogroup'
fs/tar/tar.mk:13: recipe for target '/home/user/buildroot/output/images/rootfs.tar' failed
make: *** [/home/user/buildroot/output/images/rootfs.tar] Error 1


This happens after make clean and make.
Any ideas?

Cheers,
