[gthumb-list] Can I 'root' gthumb away from my home directory?

[Chris Green <cl isbd net>]

I have just started using gthumb (because it's the default on xubuntu
11.10) and I'm quite taken with it.  

I have a question/need though, is there any way I can tell it to 'start'
as it were at a directory that's not my home directory?  I simply want
it to view the tree from $HOME/pictures downwards and not be distracted
by the rest of what's in my home directory.
