No. I did a "zypper up" with only the two needed repositories. The updated
package is in fact libgtk-3-0.

"zypper dup" wants to install 113 packages, however "zypper dup
--no-recommends" reports "Nothing to do.". I do not need these recommended
packages.

I did a "zypper in -f libgtk-3-0" and got the same error message.
