Bug#493665: Crash with libnautilus-extension1 2.22 and nautilus 2.20

[Günther Brammer]

Package: nautilus
Version: 2.20.0-6
Severity: minor

I downgraded nautilus from 2.22 to 2.20 because a webdav share didn't 
have gvfs in it's whitelist (I think.), and I got this message:

nautilus: symbol lookup error: 
/usr/lib/nautilus/extensions-1.0/libnautilus-burn-extension.so: 
undefined symbol: nautilus_file_info_get_vfs_file_info

The issue went away after I downgraded libnautilus-extension1 from 
2.22.5.1-1 to 2.20.0-6. 

I also tested the combination of libnautilus-burn4 2.20.0-1 and
libnautilus-extension1 2.22.5.1-1, and got this:

nautilus: symbol lookup error: 
/usr/lib/nautilus/extensions-1.0/libgnome-mount.so: undefined symbol: 
nautilus_file_info_get_drive

So it looks like there are some undeclared dependencies or conflicts 
somewhere, but I'm not sure where, and this is probably not a problem 
for people who don't downgrade nautilus.
