nautilus 2.7 browser mode just hangs

[Sebastien Bacher <seb128 aurel32 net>]

For some times nautilus just hangs on browser mode here and for some
other people too apparently. I don't know really how to fix the issue so
any hint would help.

I've started nautilus (2.7.4 with gnome-vfs/eel/... uptodate too) in gdb
(run --browser) and ctrl+C it to get these backtrace. The spatial mode
works fine

I get these messages in the gnome-terminal where I run it:

"** (nautilus:4509): WARNING **: Can't find description even for "x-
directory/normal". This probably means that your gnome-vfs.keys file is
in the wrong place or isn't being found for some other reason."


Any help to debug this would be welcome.


Thanks,
