unity-tweak-tool crashed with AttributeError in refresh(): 'NoneType' object has no attribute 'get_boolean'

Can you run the following command in a terminal?

      dpkg --get-selections |grep unity-lens-files

It should report:
      unity-lens-files install

Does the output match? Your system seems to have the package unity-lens-files uninstalled. (That is my initial guess)

This bug is due to some section of code that is being rewritten to prevent bugs and for better maintainability.
I will try my best to fix the bug in less than a week from now. Thanks for your interest in unity-tweak-tool.

When fixed, the tool will 'grey-out' the settings that are problematic or missing and continue to function normally.

I've installed latest build of raring(amd64) today. installed UTT, but the same bug exists, tried to reinstall it and also reinstall unity-lens-files, but with no luck.

This bug has been fixed in the PPA but is yet to be released in the repository. Can you confirm if you have our PPA enabled?

Also, it would help if you attached the output when the program is run from a terminal.

yes, it works through ppa. i had before the one from software center.
cheers

For me too. It works from PPA.
Thank you.

Hi i am have this troble to:

    if gsettings.datetime.get_boolean('show-clock') == True:

Please may you ask how me install UTT from your PPA?

sudo add-apt-repository ppa:freyja-dev/unity-tweak-tool-daily
sudo apt-get update && sudo apt-get install unity-tweak-tool

If you use askubuntu.com or ubuntu community on google plus for such things, you will get quick replies- just a suggestion.

Thank you
