Hi George, See inline responses. On Tue, Sep 16, 2014 at 1:50 AM, Γεώργιος Τρακατέλης <trakatelis@uom.edu.gr> wrote: > Dear Mike, > > Two things. > > 1.

Done: 4.0.3.0-pre01. The debug build is available too, and I manually updated the shortcuts in the debug build.[1] http://code.x2go.org/releases/binary-win32/x2goclient/previews/4.0.3.0/ I will now announce this on the mailing list. > 2.

It is bug #397! > I'm wondering why that bug was filed as an x2goserver bug instead of x2goclient. Bug #397 refers to when the user's home folder on the server has non-Ascii characters. That is why the bug is filed against x2goserver. Normally I would say that we should clone this bug (566) for X2Go Client for Linux. However, the bug report is already extremely long, I think we should just file a new one and link to this one.

If so, that test is not applicable to #397 for the aforementioned reason. In order to properly test the fix for #397 on Ubuntu, we would have to build a nightly build of x2goserver 4.0.1.16 or 4.1.0.0 from source. It is not fixed in 4.0.1.15. (AFAIK, there are no automated nightly x2goserver builds for Ubuntu. Only for Debian, Fedora and EPEL.[2]) Besides, our "fix" for #397 is not to make homedirs with non-Ascii characters "work". Our "fix" is to present a better error message and cleanly abort the session. -Mike#2 [1] http://wiki.x2go.org/doku.php/wiki:development:build-howto-mswin:x2goclient#build_x2go_client_from_source_debug_build [2] http://jenkins.x2go.org:8080/view/Server/
