nautilus vs dolphin on hardy

[larry <larrym mantic org>]

Hello!

I am using ubuntu hardy with kde 3.5. I was disappointed to find dolphin 
replaced nautilus for whatever reason and I don't really care for 
dolphin so I added nautilus from the repos (I am using 2.2.2) but on a 
few occasions nautilus fails to load and I get err msgs about GLib and 
something like 'synchronization fault'.

I googled a bunch of ubuntu and *nix pages and it seems this is not a 
rare problem. I could find no concise description as to the cause, but 
it seems that either hardy and/or kde 3.5 is somehow not as friendly for 
nautilus as feisty or gutsy. I did run apt-get clean and that did not 
resolve the problem, but rebooting seemed to.

I would appreciate some comment as to whether the nautilus/gnome 
developers can shed any specific light on this issue and tell me how to 
get nautilus to run more stably with hardy and kde 3.5.

I also have a more specific question: what function allows Nautilus to 
render icons that apparently display the first frame of video files? I 
note that this feature is not available in either Konqueror or Dolphin 
so I am curious what enables it in Nautilus.

Thanks!
