Thanks! BTW: we have developed a small test case which known results which could be used also for other software. It will be shipping soon with the source code.

I fixed it in Addons. Hence, you need to simply reinstall the addon.

You don't need to trust my answers but we spent months on bugfixing the code. There was a reason for it.

comment Intermittent multi-threading in Grass 7?
It has also been updated in GRASS GIS 6.4.4. See trac.osgeo.org/grass/wiki/Release/6.4.4-News#Majormodulechanges . I understand that the loss of parallelism is annoying but at least you get results which are comparable to Fragstats, other software, and manual computation. Before this was not necessarily the case and sometimes the results got corrupted (AFAIK broken memory management in r.li which is got fixed). In GRASS GIS we insist on quality, i.e. correct results and reliable computations!

comment Looking for guidance to create a hydrological map with QGIS and/or GRASS
OK, I now added an example how to extract a vector river network from a DEM here: grass.osgeo.org/grass70/manuals/r.thin.html - see the screenshots therein. Note that this is way less accurate than using the r.stream tools.

Could you copy the command line here? Then we'd know what you exactly tried.

The choice of the second archive ("Roads ArcReader Projects") with the projection information included is working well.
