I have the same problem on openSUSE Tumbleweed. I can confirm that deleting the /usr/lib/insync/libstdc++.so.6 library fixes the problem here, too.
However, I have a problem with the Insync repo, which may be similar to the problem other users have reported on Fedora.
Zypper reports that my insync client isn’t the latest one:
~> LANG=C zypper se -s insync
