[gentoo-user] strange lxde block

 * Error: The above package list contains packages which cannot be

  (lxde-base/lxsession-0.4.9.2::gentoo, ebuild scheduled for merge)
pulled in by
    >=lxde-base/lxsession-0.4.6.1 required by
(lxde-base/lxde-meta-0.5.5-r3::gentoo, installed)
    lxde-base/lxsession required by

    =lxde-base/lxsession-edit-0.2* required by
(lxde-base/lxde-meta-0.5.5-r3::gentoo, installed)

lxde-meta lists:
RDEPEND="...
        =lxde-base/lxsession-0.4.6.1
        =lxde-base/lxsession-edit-0.2*

lxsession lists:
RDEPEND="${COMMON_DEPEND}
        !lxde-base/lxsession-edit

So lxde-meta requires lxsession-edit and lxsession, but lxsession lists
lxsession-edit as blocker. Is it a bug in the ebuild?
