I was finally able to duplicate your error. This happens, it seems, only
when working in a longitude/latitude location. When I used two DEM
rasters in a *projected* location, the interpolation to high-resolution
in the area covered only by the lowres raster worked fine. (Also if the
lowres raster extends in two directions).
However in a Long/lat location, with units of degrees, the addon fails.
I looked thru the source code, and my guess is that there is something
in the conversion from interpolation area to vector lines that is
failing. I'll report to the maintainer.
In any case, would you want to try to transform your DEM rasters to a
projected location and rerun the module?
One caveat: be aware that interpolating a full SRTM tile (approx 110km x
110km) to a resolution of 1 meter will create a huge raster (if my
numbers are right, it would be about 50GB) and would take a very long
time. So I'd suggest to try this out first in a much smaller area.

No solution yet :-(, only more questions...
It looks to me that the plugin is intended to work when the lowres
raster extends the highres raster only in one direction. In your
case,
the 1 degree SRTM tile you are using totally contains the USGS 1
meter
region.
To test this I would try to clip out a section of the SRTM:
# Set the computation region to the highres raster, then extend
only in
one direction
g.region -p rast=USGS_one_meter_x39y445_IL_12_County_ChampaignCo_2008
g.region -p w=88:20:00W
# Now clip the SRTM to this new region
# But use the coarse resolution
g.region -p res=0:00:01
r.mapcalc "n40_w089_clip = n40_w089_1arc_v3"
# Now try r.mblend with this clipped SRTM
r.mblend high=USGS_one_meter_x39y445_IL_12_County_ChampaignCo_2008
low=n40_w089_clip out=blend
Please report back if this helps (or not...)
