This relates to problems with g.version (#2351) and new, more strict error
handling (#2326). I tried to fix g.version in r61589 but I'm not sure if I
was successful, now it seems that I was not. I'm also not sure what r62747
changed in g.version checks. (Note: Both changes are backported to release
branch 7.0.)

At least the error handling now gives us the idea about what's happening.
-11 means segmentation fault on Ubuntu AFAIK, so it is really related to
#2351.

I changed the error handling to "ignore" in r62822 (and backported). It
reintroduces the original behavior before #2326. Although it might be
appropriate in this case, the better solution would be to fix g.version as
r61589 was trying to do.
