[GRASS-dev] Error reading null row 2725 for <MASK>

When running several r.mapcalc in a loop (via R) the function stops with an
ERROR: Error reading null row 2725 for <MASK>
The row number varies. This seems to happen at random, and when I repeat
the same r.mapcalc calculation that stopped with the error before, things
run without problem.
I tried after removing the mask, and this time no problem so it may have to
do something with the MASK? (as these error messages only occur once in a
while, I can't be completely sure it only happens when a MASK is defined).
I ran it through R, using the execGRASS() function of the spgrass6 package.
I ran the same, but using the system call instead of execGRASS. Still got
the same error messages. I therefore guess this has nothing to do with R?
