Description Jens Knutson 2010-05-11 03:36:04 UTC 
Quick python example demonstrating my problem

>>> import dbus
>>> bus = dbus.SessionBus()
>>> gnote_proxy = bus.get_object('org.gnome.Gnote', '/org/gnome/Gnote/RemoteControl')
>>> gnote_proxy.FindStartHereNote()
Traceback (most recent call last):

+ Trace 221853

  • File "<input>", line 1 in <module>
  • File "/usr/lib/python2.6/site-packages/dbus/proxies.py", line 68 in __call__

(and then Gnote crashes)
Comment 1 Aurimas Černius 2010-12-14 21:26:18 UTC 
Actually Gnote aborts because of uncaught exception. Unfortunately this exception seems to be thrown out from main loop, it's an internal Gnote exception.
Looks like this exception is thrown by dbus-c++ library, I reported this bug to them:

Comment 2 Aurimas Černius 2011-08-26 18:37:08 UTC 
The provided example is not the correct way to use gnote D-Bus API from python.
Gnote D-Bus support have been ported to Gio::DBus, this problem is gone.
Thank you for bug report.
