This is broken with =dash-0.5.8.1-r2 but works with older versions/revisions of dash. As a result of x2gopath not working correctly many of the other scripts x2goserver uses break as well.
Oh, I forgot to mention that this only happens when /bin/sh points to dash.
x2goserver is broken. you cannot rely on the -n option to echo.

If the first operand is -n, or if any of the operands contain a backslash ( '\' ) character, the results are implementation-defined." "On XSI-conformant systems, if the first operand is -n, it shall be treated as a string, not an option. The following character sequences shall be recognized on XSI-conformant systems within any of the arguments:" "DASH Description DASH is a POSIX-compliant implementation of /bin/sh that aims to be as small as possible. It does this without sacrificing speed where possible. In fact, it is significantly faster than bash (the GNU Bourne-Again SHell) for most tasks." So IMHO "-n" should be supported and work here as expected.

"APPLICATION USAGE" seems to clarify that.
Upstream fixed this issue: http://code.x2go.org/gitweb?p=x2goserver.git;a=patch;h=90bbbb6f9c21386c4d576e0f017c59a25aa7de9b
Upstream seems busy with reorganization stuff, so I added the patch in x2goserver-4.0.1.18-r2!
