Bug#856036: screen sharing is not working and vino is segfaulting when started manually

package: vino
version: 3.22.0-1
severity: grave
justification: makes the package unuseable

I'm not able to share desktop using vino (5900 socket is not open) and
when I manually start vino-server I get segmentation fault

Here is a backtrace from gdb.
