Package: xvnc4viewer Version: 4.1.1+X4.3.0-38 Severity: grave Dear Maintainer,
since the last update, vncviewer crashes when I try to connect (output appended below). I think the problem is caused by the viewer and not by the server ("vnc4server 4.1.1+X4.3.0-37.6 i386" on a Debian stable host), because connecting is possible from the host itself with the viewer from stable. Downgrading the viewer on my system to "4.1.1+X4.3.0-37.6 amd64" fixes the problem.
