Crash on start if default keyring is locked

[Bertrand Lorentz]

For some reason, my default keyring is not unlocked automatically when I login.
So, if I start Polly before unlocking it, Polly crashes with the following stacktrace:

If I unlock the keyring with Seahorse, then Polly works fine.

[Conscious User (conscioususer)]

I will confirm this later at home, but IIRC python-keyring indeed assumes that the chosen keyring is unlocked.

But what is weird is that the error message does not seem directly related to that, but to the fact that PyGI is incompatible with PyGTK2. Why is this error not being triggered when the keyring is unlocked? Does it use an older library in that case? Does not make sense, I need to check that out...

Oh, and which distro are you using?

[Bertrand Lorentz (bertrand-lorentz)]

I'm running a fully updated Ubuntu GNOME 13.10, along with the updates from the related GNOME3 PPA:
https://launchpad.net/~gnome3-team/+archive/gnome3

I don't know much about python, but maybe because the keyring is locked it goes into another code path which then tries to load PyGI ?

[Bertrand Lorentz (bertrand-lorentz)]

I've now upgraded my system to Ubuntu GNOME 14.04, and the same thing happens: keyring not unlocked, polly crashes.
But the error message is different at the end, so here it is:

I can confirm this.

Then adding an account with a locked keyring I would get this stack trace.

Using seahorse did not unlock the keyring for me.

I finally had to unlock it using the following python code:

$ python
>>> import gnomekeyring
>>> gnomekeyring.unlock_sync(None, 'mypassword');
