Hi, i solved the problem.
After downgrade of gtk-sharp and glade-sharp to version 2.8.2 openvpn-admin works correctly.
previously i try only 2.12* builds, whitch doesn't works.
Maybe 2.10.* may work too, but i not tested that.
Good luck.
Hi, i have the same problem...
i try compiling with various mono, gtk-sharp versions, but without success.
It happend after global system update.
I think there is a problem with some dependend library and it's version.
Binary packages don't work for me too.
