Description
Most image formats handled by goblin are stored on disk in a different layout than they'd actually appear in memory if mapped for execution.
At least for PE, pointing goblin at an image that has been loaded into memory results in it erroring out (during processing imports, but i didn't look closer). It would be nice if it Just Worked.
btw, looking at the ImageBase field in the header and comparing to the address of the base of the PE is a reliable way to detect if you're parsing an on-disk image or one which has been loaded.

Research direction
Start by locating goblin's PE parsing and import-processing entry points, then trace how section layout and the ImageBase field are handled. Compare parsing an on-disk PE with an image loaded into memory, using the ImageBase and base address as the issue suggests. Done means loaded PE images parse successfully, including imports, without regressing on-disk parsing.
