xpra unstable

[Rolf Leggewie]

I've only recently discovered xpra. I use it between two machines that are both running precise. The version I have installed is 0.0.7.36+dfsg-1. I get many python errors on the command line. Quite frequently, they are fatal and I have to reattach to the session. Here is one of them.

I was running pidgin in that xpra session. Xpra crashed when I double-clicked on an IRC group. While I entered the group the xpra session crashed with above error.

Here is another (non-fatal) error

$ /usr/lib/xpra/xpra/client.py:168: GtkWarning: IA__gtk_window_set_type_hint: assertion `!gtk_widget_get_mapped (GTK_WIDGET (window))' failed
  self.set_type_hint(hint)

and another one when detaching from a session.

$ xpra detach ssh:laptop:74
Enter passphrase for key '/home/rolf/.ssh/id_dsa':
Exception in thread read_loop (most likely raised during interpreter shutdown):
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 551, in __bootstrap_inner
  File "/usr/lib/python2.7/threading.py", line 504, in run
  File "/usr/lib/xpra/xpra/protocol.py", line 245, in _read_thread_loop
<type 'exceptions.TypeError'>: 'NoneType' object is not callable

Why do I have to enter password credentials when detaching from a remote ssh-session anyhow, I wonder?

[أحمد المحمودي (Ahmed El-Mahmoudy) (aelmahmoudy)]

That is a very old version of xpra

[Rolf Leggewie (r0lf)]

Ahmed, good to see you. How are you doing?

0.0.7.36+dfsg-1 is the latest, up-todate version available in precise LTS (which itself was released less than a year ago).

I'll see if I can backport a later version of the package for testing. Nonetheless, the version in the LTS is what it is.

[أحمد المحمودي (Ahmed El-Mahmoudy) (aelmahmoudy)]

I'm fine thanks.

Quantal & Raring have 0.3.11+dfsg-1.
Personally, I am using 0.7.5+dfsg-1 which I got from Debian experimental.
Latest on Debian experimental is 0.8.8+dfsg-1 but it can't be sync'ed easily to Ubuntu since it requires libav 9.1

[Rolf Leggewie (r0lf)]

I managed to backport the package from unstable to precise without much trouble. I'll let you know how it goes.

When installing said package, I noticed that a bunch of multimedia-related packages were being pulled in. Overall about 20MB worth. I don't need multimedia remotely and would appreciate if xpra packaging could be modularized to allow finer control.

Thank you for maintaining the package.

[Rolf Leggewie (r0lf)]

The error from comment 1 is still present. I'll report back if I experience any stability issues.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[peter swain (swine)]

upstream xpra seems stable, after a small tweak ...

Because ubuntu starts "Xsession true", 2 args.
Now to turn that into a dpkg (tomorrow?)
