light-locker-settings reverts to "never" after reboot.

[Bib]

Hi
I'm trying light-locker after I upgraded to Trusty because I don't want the locked screen background to be the same as my desktop wallpaper.
I find that "Blank screen after" and "Switch off display after.." both reverts to "Never" after I reboot my system and Super+L won't display the same background as light-dm when the system is powered on.

Hi, can you give me a bit more information? Are you using Ubuntu, Lubuntu, Xubuntu, something else?

I can confirm this issue on Arch Linux. Here is the traceback:

Traceback (most recent call last):

I can also confirm this behaviour on Arch Linux. Light-Locker-Setting will not store the changed settings after they are applied.

[Rainer Müller (raimue)]

The problem is that light-locker-settings fails if the expected file does not already exist. There is a simple workaround by creating an empty file in that location before launching light-locker-settings:

    $ touch ~/.config/autostart/screensaver-settings.desktop
    $ light-locker-settings

I am also attaching a patch that kind of solves this problem by masking any error that the load function might raise. I do not really understand the GLib python bindings here, though. Apparently it is supposed to return an error code, but at the same time it always raises a generic GLib.Error, so the return value cannot be checked at all...?

The attachment "light-locker-settings-ignore-error.diff" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.
