I have Insync 3.2.9 running on an openSUSE 15.2 system with xfce 4.14 and it works fine.
On another system upgrade to openSUSE 15.2 from 15.1, switched to xfce 4.14 from kde 5.18.
If I log into KDE session Insync (3.2.9) works fine, if I log into xfce session Insync (3.2.9) fails to start and I get the following error (insync start --no-daemon)
/usr/lib/insync/insync: symbol lookup error: /usr/lib64/gio/modules/libdconfsettings.so: undefined symbol: g_log_structured_standard
For now I’m logging in with kde.
Help appreciated to resolve this issue.
