[BUG] DBus + Ubuntu 10.04 Alpha-3

[lacyc3]

Hi!

I can't decide that this is  the right place for DBus plugin bug or the Support, so I'm sorry if it's not the right place.

OS: Ubuntu 10.04 - Alpha 3 with latest updates.
Emesene: 1.6-1

After activating DBus plugin, emesene complain that:

Code:

Exception
You are using emesene 1.6 "mate" so you're free to complain here:

KeyError: "Can't register the object-path handler for '/org/emesene/dbus': there is already a handler"

There is some message in the terminal.

Can you try using the svn version? Maybe that's fixed, there was some changes on the DBus plugin since 1.6.1 release. You can download the source from here http://emesene.svn.sourceforge.net/viewvc/emesene/trunk/emesene/, untar and run emesene file.

Yes, i tried and only one error in the console (and not in popup window):

Code:

emesene/plugins_base/Plugin.py:75: Warning: /build/buildd/glib2.0-2.23.4/gobject/gsignal.c:2385: instance `0x9e82560' has no handler with id `2951'
  self.msn.disconnect( callbackId )

Today my emesene freezes while chatting and I've seen this error in console... can it be the cause?

[lacyc3]

I think no. I have been using emesene since I reported this line without any problems.

[arielj]

That error shouldn't be the cause of the exception, it's just a disconnect from a signal that's not connected... some plugin is trying to disconnect a signal with an invalid ID, but there's no clue of the plugin that calls that disconnect, can you disable all the plugins and leave only the DBus plugin to see if that happens again (it should happen only when disabling the plugin, that's when the disconnections are invoked on DBus plugin)? I can't test it because it doesn't work on Windows...

EDIT: are you sure that it happens also with the latests plugin version? because the exception points a line that's not the same on the actual DBus plugin and the actual DBus plugin already handles exceptions raised on that method...

If the first exceptions disappears then it's fixed, please confirm that. The second error wouldn't crash emesene, it's just a bad handle of a signal, it's another bug, but it's not that important and we need to know if it's caused by the DBus plugin or what.

[lacyc3]

Arielj: You're right of course. Thx for the very quick bugfix and answer

[arielj]

ok, thanks, that warning on the terminal is another bug, and it's just a warning, won't hurt anyone for now

[karasu]

Well... I've disabled the D-Bus plugin and no more freezing... :S

Maybe it's a coincidence... I'll try to find what's causing this.

[ukblacknight]

Has this started just recently?  I've had some patches applied to DBus recently, but I've not been experiencing any freezing or crashes.  I'll give it a go in Lucid.  What have you got interacting with emesene via dbus?

[karasu]

Hi!

Yes, this just started yesterday. Anyway, I don't know what is the cause. Let me test it a little bit more, but I can't imagine how the D-Bus plugin could freeze my emesene.

I'm positive must be something else.

Forget about it... I'll tell something if I'm certain that D-Bus plugin is faulty.

Thanks for your interest!
