Package: nxagent
Version: 3.5.99.26-1
Severity: important
Tags: patch
Fixed: 3.5.99.25-1
For some unknown reason, upstream discovered a regression in nxagent
(aka x2goagent with X2Go). When connecting to an existing X11 session
("connect to local desktop"), one gets an nxagent/x2goagent crash:
```

```
It is 100% reproducible, 3.5.99.25 worked fine.
The upstream issue is at https://github.com/ArcticaProject/nx-libs/issues/1009
Patch for this (a commit backported from X.Org) is attached.

Subject: [PATCH] randr: Do not update ConnectionInfo if NULL
Backport of this xorg-xserver commit:
commit 941aeb3b92e644923bd112eef8023f033a140ee6
Author: Olivier Fourdan <[email protected]>
Date: Fri May 13 08:58:58 2016 +0200
randr: Do not update ConnectionInfo if NULL
RRScreenSizeNotify() will update the connection information block, but
if this occurs during initialization before ConnectionInfo is even
initialized, this will lead to a crash.
Simply check for ConnectionInfo prior to update it to avoid the crash.
