[winswitch] XPRA 0.16.2 - Stability issues & status of non-US keyboard support ?

Tue Mar 15 18:29:26 GMT 2016

Hi there,

I am still exploring xpra at the moment (see earlier post about xpra 
stop issue). Currently I am fighting with an issue regarding keyboard 
support.

For the tests I am using Google Chrome 48, Internet Explorer 10 and 
Firefox 38.7 as client browsers under Windows 7. My local keyboard 
layout is "ch". XPRA server runs under CentOS 7.2 and I am using the 
HTML5 interface with AES Encryption and Password protection to connect. 
My test example is to run a simple xterm in a browser.

Chrome and Firefox do detect a "us" keyboard which is wrong. The 
sessions in  both browsers run stable though. Internet Explorer 10 
however correct detects "ch" keyboard and launches the session. I can 
see the xterm window coming up but as soon as I move the mouse pointer, 
the session disappears and displays the connect.html page.

In the logs (with "--debug=ALL" in the xpra start command) I can see the 
following lines.

-------------------

Error parsing bencode packet:
invalid literal for long() with base 10: '407.3333435058594'
Disconnecting client '127.0.0.1:33448':
failed to parse bencode packet
xpra client disconnected.

-----------------------

Questions:

1) Why do Firefox and Chrome detect "us" keyboard instead of "ch" ? I 
have been playing with various input-methods but did not have any success.

2) What is the issue with Internet Explorer and the error in the bencode 
packet. XPRA server is the same in both cases.

Happy to supply any logs and data you may need.

Many thanks in advance,

Michael.
