light-locker crashes at unlock every time I run it from the command line.

What happens when you run light-locker from the command line?

I agree that it should not normally be run from the command line.  I wanted to run lightlocker with different options and the running it from the command line was faster than logging on and off.

I tried running light-locker in gdb but that hung my session and I had to login on another console and kill gdb to recover.

I think that light-locker should either run correctly from the command line or announce that it cannot be used that way.

thanks, Stuart

This is normally a bug in some application using the D-Bus library.
