Yup, I've observed this also since openSUSE:Factory migrated to GNOME 3.20 with
the newer libsigc++ & glibmm that required the c++11 standard and broke our
build. After the build fix, copy/paste and drag/drop have failed.

This will need to be investigated further to determine why this would have
broken copy/paste and drag/drop.
