Comment 4 for bug 940715

@~suv thanks for testing, fixes in the attached patch

> The window on the left with the "list of nodes" has a 'too wide' minimal width
Yes true, this can now be resized much smaller

> minimal width of the node list in the docked dialog is also wider
I have reduced the minimum size here as well. The dialog still has a minimum size so that is looks ok when docked

> the dialog seems to use different gtk-settings for frames
Good spotting, i have fixed this to be consistent with the old dialog and other docked dialogs.

>Sometimes I get an additional empty field in the dialog
This should be fixed in this patch.
