You try to overwrite the source with the target, to my knowledge invalid
(sure, the module should say so).
Try
r.fillnulls input=dtm1 output=dtm1_filled

I used the --overwrite option
i had problems with r.fillnulls recently see :
http://osgeo-org.1560.n6.nabble.com/r-fillnulls-error-lt-z-gt-is-not-a-valid-flag-grass7-td5034768.html
after that fix the same syntax was working
changing the output to a new name i got the same error

Try to remove zcol = 'value' from the call to v.surf.rst in the
r.fillnulls script. The vector created by r.fillnulls with r.to.vect
is 3D, so no z column is needed (or present).

Tested, this solves the problem. I guess it is an artifact of the -z usage
in the GRASS 6 version or the r.to.vect usage.

thanks this fixed my problem!
