Ok. Do you have any plans to offer a fix for #234787 for sarge? This seems like a significant issue that it would be a very good idea to have fixed in the next point release. I agree that it sounds like there's also a GNOME bug here.

There's no guarantee of that; he may have still been running the version that released with sarge.

There have been some problems with gamin, including problems where gamin was *not* ABI compatible with fam; IIRC, this was the reason gamin didn't ship with sarge. Hopefully, these will be sorted out so that we can get a smooth transition. -- Steve Langasek postmodern programmer
