This bug is (AFAIU) from the same series of underspecified RPM dependencies
(collected at https://bugzilla.altlinux.org/show_bug.cgi?id=15079 ): in reality,
the program needs a new version of a library, in RPM, this isn't specified. 

The reasonable solution should probably be to add the version to the library's
ABI and to rebuild this package; in this case, the library is a part of gtk (I
haven't found out which one).
