breaks application when Gtk3 is also used

[Jelmer Vernooij]

keyring imports the gnomekeyring module, which uses gtk2.

This breaks any Gtk3 applications in which it is loaded.

Python 2.7.2+ (default, Oct 4 2011, 20:06:09)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import keyring
>>> from gi.repository import GOBject
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/gi/__init__.py", line 23, in <module>
    from ._gi import _API, Repository
ImportError: could not import gobject (error was: ImportError('When using gi.repository you must not import static modules like "gobject". Please change all occurrences of "import gobject" to "from gi.repository import GObject".',))

I'm not sure what the best solution is to work around this - it seems pretty hard to determine if the current application is a gtk2 or gtk3 app, especially if keyring is imported before Gtk. It would be nice if there was at least some way of disabling the GNOME backend for keyring, so applications that are aware of this issue can work around it.

This makes it impossible to do anything that involves launchpadlib in e.g. bzr's Gtk frontends.

A workaround is to change importing order:

>>> import gnomekeyring
>>> from gi.repository import Gtk
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/gi/__init__.py", line 23, in <module>
    from ._gi import _API, Repository
ImportError: could not import gobject (error was: ImportError('When using gi.repository you must not import static modules like "gobject". Please change all occurrences of "import gobject" to "from gi.repository import GObject".',))

--------

>>> from gi.repository import Gtk
>>> import gnomekeyring
/usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed
  import gobject._gobject

In this way we don't get crash, only a warning message.

Also, Stef (Gnome Keyring developer) works on a new library (gsecret) that will suport introspection: http://stef.thewalter.net/2011/09/introspecting-certificates.html#c5364051270673968069.

I hope this will be ready for Precise.

I've already been looking at using the secret service DBus interface, see the bitbucket bug for details.

[Dmitry Shachnev (mitya57)]

@Jelmer: any plans to finish the secret service backend?

[Jelmer Vernooij (jelmer)]

Yes, it's on my list of things to finish.

FYI, I use some of your code in my mailsender script:

This has been fixed in python-keyring 0.9.0.
