Subject: X2go server crashes on Ubuntu 16.04

package: nxagent
Version: 3.5.99.15-0~201803072246~ubuntu16.04.1
Severity: grave

We have the same problem here after upgrading x2go from 4.0.1.22 to 4.1.0.0.

It is independent of client version and OS (both Linux and Windows), and
seems to be related to Xinerama:

- when enabling Xinerama support in the client, x2go works in
fullscreen, but leads to a crash in windowed mode as soon as the window
is resized or moved to a different display.

- when disabling Xinerama support, everything seems ok

The log shows a segfault of nxagent, exactly as described above.
