Today I started luckybackup for the first time in few weeks. And I can start it only as root both from menu and from console. I think it has changed in KDE 4.4, but there may by another reason.
I'm using fully updated Fedora 12 with KDE 4.4.0.

When you run it as a user, does it output any error messages?

I run it as a user, but then opens a window asking for root password, no errors.

Does the root privilages dialogue look similar to this?

Or this?

It's more less the first example. It says, translated to English: you tried to run luckybackup which requires root privileges, enter the password. But there's no possibility of continuing as normal user.

This is likely a decision by the developers of luckybackup. I suggest you contact them.

OK, I will do this now.
Thanks for help

I've just cleared things out. This is not a developer's change. Luckybackup included in updates repository is broken. Or maybe it's meant to be this way? After removing that and installing original package from developer everything is back to normal.

Please inform your distribution of this ( or the maintainer of the repository if third party ) so that they can correct this.
