Gentoo had a similar problem about a year ago and it was solved with:
Fixed after upgrading udisks to sys-fs/udisks-2.7.5 and sys-libs/libblockdev as static, and other "helper" fs programs that libblockdev might need. The latter steps probably not necessary. Anyway all functional now.

Maybe there are some missing updates for similar files.
Cheers
Bill
