[Python-apps-team] Bug#710868: xpra: does not show password prompt unless I install ssh-askpass-gnome

[Timo Juhani Lindfors]

Package: xpra
Version: 0.9.4+dfsg-1
Severity: normal

Steps to reproduce:
1) Disable any SSH keys
2) xpra attach ssh:server.example.com:7

Expected results:
2) user sees a password prompt

Actual results:
2) user does not see any password prompt:

xpra client version 0.9.4
2013-06-03 06:34:27,619 check_server_echo: server is not responding, redrawing spinners over the windows
2013-06-03 06:35:25,619 server ping timeout - waited 60 seconds without a response
2013-06-03 06:35:25,621 connection closed after 0 packets received (0 bytes) and 7 packets sent (8512 bytes)
2013-06-03 06:35:25,623 Connection lost
2013-06-03 06:35:25,707 check_server_echo: server is OK again, stopping redraw

More info:
1) ps axuf shows that ssh-askpass gets started but somehow it does not
   seem to be visible to the user:

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

lindi    31505  0.0  0.0  24684  1460 ?        S    06:34   0:00  |                           \_ /usr/bin/ssh-askpass lindi at server.example.com's password:


2) After xpra timeouts the ssh-askpass process is left running and
   orphaned:

lindi    31499  0.0  0.0  45936  2944 ?        Ss   06:34   0:00 ssh -T server.example.com .xpra/run-xpra _proxy :7
lindi    31505  0.0  0.0  24684  1460 ?        S    06:34   0:00  \_ /usr/bin/ssh-askpass lindi at server.example.com's password: 


3) If I install the "ssh-askpass-gnome" package then I get a popup that
   properly asks for a password. However, if I spend more than 8 seconds
   typing the password then xpra timeouts:

xpra client version 0.9.4
2013-06-03 07:02:57,681 check_server_echo: server is not responding, redrawing spinners over the windows
2013-06-03 07:03:25,701 connection closed after 0 packets received (0 bytes) and 5 packets sent (8431 bytes)
2013-06-03 07:03:25,703 Connection lost
2013-06-03 07:03:25,773 check_server_echo: server is OK again, stopping redraw

   This is probably related to the previous bug I reported:
   http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=710866

   I'm using one-time passwords so it is quite a challenge to type them
   in 8 seconds ;)
