Keyring/DBus doesn't work with mate-keyring

[L. Böger]

In a MATE desktop environment, there is by default no gnome-keyring running but the corresponding mate-keyring. The python keyring module doesn't seem to work with mate-keyring: When requesting the password for Mint-Integration (mint/kring.py, line 30), an error occurs with the following stacktrace:

The dialog to edit currency, recurring transactions or mint integration doesn't pop up. This is for wxbanker 0.9.1, running on Linux Mint with mate-keyring 1.3.0-1, python-dbus 1.0.0-1 and python-keyring 0.9.2-0.

Thanks for the report! Is this stock Linux Mint and if so, what version? Just let me know what I need to install the reproduce this and I should be able to fix it.

[L. Böger (lubgr)]

Yes, it's Linux Mint 13, kernel 3.2.0-58, 64 bit, and the MATE desktop installed. If you install gnome-keyring in addition to mate-keyring, it works, otherwise it crashes.

[Michael Rooney (mrooney)]

Okay, thanks! Do you think a reasonable fix would be to just add gnome-keyring to the wxBanker depends, if that's all it takes to work with your system?

[L. Böger (lubgr)]

My understanding is that the python keyring utility uses the keyring of the installed desktop/system, such that adding gnome-keyring to the wxBanker dependencies would enforce gnome-keyring being installed on a KDE system that originally used KDEKWallet. However, I don't know a better solution than adding the dependency.

[Michael Rooney (mrooney)]

Okay, it looks like python-keyring supports KDEWallet but not mate-keyring. Instead of having a dependency for KDE users on gnome-wallet, I'll just see if I can properly support mate-wallet.
