Sorry - you did indeed ask what repo libdbus-1-2 is in - silly me.

Now that I have it installed, I am not sure how I can figure out what repo libdbus came from. If there is an easy way to tell, let me know and I will establish which one it was and get back to you.

Failing that, I can tell you which repos I have configured in app manager: basically all 20 OS2008 repos listed at:
http://gronmayer.com/it/index.php?lang=en&system=maemo4

I was assuming (erroneously apparently) that it was in one of the pre-installed repos, but apparently not. But it must be on one of these 20.

So if you click to install all 20 of these in one go, and then go into red pill mode, I believe you will find the relevant lib, and pretty soon a chuckle will be forming in your belly. As it were.

I do hope this helps, and good luck!
