I managed to track down the source of the issue. It looks like gnome vfs has an issue with my system.
Specifically, inkscape was hitting the following in src/file.cpp on line 762 when I attempted to save_as() via the dbus interface: g_warning("Could not find the temp saving.");
I'm not sure what gnome vfs brings beyond access to remote clip art and usage of /tmp (https://bugzilla.redhat.com/show_bug.cgi?id=653516), neither of which I need, so I disabled it on my local build: $ ./configure --enable-dbusapi --with-gnome-vfs=no
After recompilation, my dbus test case -- specifically save_as() and save() -- works as expected.
Thanks all.

Hi All,
TL;DR I've put forth some solid effort on the following, but need help:
- how do I properly compile Inkscape 0.91 with DBus enabled?
- I'm getting errors calling basic methods using the DBus API, eg. save()
and save_as(), are others seeing this?
- is the DBus API maintained?
__ Some background first: __
My goal here is to automate some repetitive tasks across tens of thousands of SVGs. My approach uses a combination of these methods/verbs: load, selection_ungroup, object_to_path, selection_combine (union and exclusion), select_move, save_as.
This is my first attempt at compiling Inkscape and using the DBus API, so I suspect the problem probably lies on my end. I'd appreciate pointers to help correct my ways.
__ What I've done: __
I'm running an Ubuntu 14.04 image within VirtualBox. Here's how I've compiled Inkscape. Also I show a simple DBus test case, via python, which fails on save() and save_as().

__ Help? __
Back to my initial Qs. Am I setting up prereqs and compiling Inkscape correctly to use the DBus API?
Is the above test case reflective of a known issue on the DBus API or am I in the wrong?
If it looks correct, I'm wondering if the DBus interface is still maintained, or incomplete, or subject to a regression?
I'm hoping to sort this out for my purposes, but also think that this would generate a helpful "how-to" for anyone wishing to get DBus up and running on 0.91.
Cheers and congrats on 0.91!
