Sooperlooper loses connection to engine

If it happens that sooperlooper shows you this dialog:

Lost connection to SooperLooper engine.
See the Preferences->Connections tab to start a new one

on newer distributions (I tried it with Fedora 16 beta 1), add your
. (substitude with your host and with your domain) to your `/etc/hosts' file on the line for 127.0.0.1 and try again.

For example, my hostname is `mmxgn' and domain is `emergencia' so my hosts file was:

127.0.0.1 localhost.localdomain localhost

and I added mmxgn.emergencia next to localhost.

127.0.0.1 localhost.localdomain localhost mmxgn.emergencia

Now when I run `slgui' I can use sooperlooper without the engine dying.
