yep - that's the one. So the bug is identified. But what is even more weird is that I did restore my setting as reccommended by Johsua and ziltch, no RSS feeds came back. Nothing changed.
That bothers me even more. Does this mean that the restoring mechanism is also unreliable?!
I have never seen this kind of stuff happening with all the versions of Debian I have used (Sarge, Kanotix, Knoppiux, Ubuntu, DSL and, of course, gNewSense). I mean - config files don't just disappear like that "poff!" and we are gone! I just hope that is is some r/w issue with the RSS news reader and not some issue with the filesystem or something... (though I read somewhere that N800 actually has a journalling filesystem).
Guys - what is your experience with the backup/restore utility? Is this one buggy too, or just it just not backup all the settings?
