Have you tried this on windows? That dll isn't provided by windows, it's likely an application bug.
No, when I have some time I'll have a go at installing Win XP in a KVM (Moved all my genealogy projects over to the linux version of Gramps from TMG(The Master Genealogist) and no longer have windows installed)
The dll is provided by gtk-dev-2.12.9-win32-2.exe looked through their bugzilla and could not find the issue.
I then went to the Ubuntu bugzilla and found something similar [Everything whick is linked against libgio-2.0 core dump] https://bugs.launchpad.net/ubuntu/+bug/402693
which relates to the linux version of libgio-2.0-0.dll (Not sure if it should be an issue for the same dll in wine on top of linux?)
I believe (for the moment) since the Gramps team have it listed as working on Windows with the steps they describe that it should.
