file dialog 'up' can go past root
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
If I open a file dialog, and hit the up directory button, I can go past the root directory.
So I end up with things like
c:......
or
/../../../
And navigating back into directories gives things like /../../../home/myhomedir/
Not too bad of a problem, since files can still be opened.
