Kxdocker weird circular dependency

When I try to emerge kxdocker under overlay "portage-xgl", a weird circular dependnecy occr:

kde-misc/kxdocker-1.1.4a-r1 depends on

kde-misc/kxdocker-i18n
kde-misc/kxdocker-resource
kde-misc/kxdocker-i18n depends on
kde-misc/kxdocker
kde-misc/kxdocker-resource
kde-misc/kxdocker
Maybe I use "nls" in my use flag to cause this situation, but the dependency looks very very unreasonable, and i update the portage-xgl to the newest version. So I decide to use brute force to solve it XD~
Edit kde-misc/kxdocker-1.1.4a-r1.ebuild, remove the RDEPEND.
After that, all the problems was solved!
