Xorg restart and goes back to lightdm after entering keyring's passoword

[Nicoco]

I have automatic login and after booting I have to enter my keyring's password (even without launching any apps, I think it's gwibber requesting it)
About 50% of the time, system hangs for 2 seconds instantly after I validate my password and goes back to my login screen (lightdm). I'm pretty sure it's a Xorg crash as I can find a backtrace in the /var/log/Xorg.0.log.org

This bug only seems to occur when I type the keyring's password really fast at login.
It looks like I've found a fix : waiting for a few seconds before entering it.
I'm not really happy about it because :
- I still don't know which app is requesting to open the keyring
- Until I've typed the password, I can't move any window (but I can launch firefox)
I'd be happy to give out more information to have this fixed.

Nicoco, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-input-evdev REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
