I changed this in v.db.addcol and it behaves somehow strange, but now it 
works....:
it creates the table, it seems to calculate right, but gives this echo:
Adding column <dgm_n>
[: 96: expr 1+1: bad number
Adding column <dgm_min>
[: 96: expr 1+1: bad number
Adding column <dgm_max>
[: 96: expr 1+1: bad number
Adding column <dgm_range>
[: 96: expr 1+1: bad number
Adding column <dgm_mean>
[: 96: expr 1+1: bad number
Adding column <dgm_stddev>
[: 96: expr 1+1: bad number
Adding column <dgm_varian>
[: 96: expr 1+1: bad number
Adding column <dgm_cf_var>
[: 96: expr 1+1: bad number
Adding column <dgm_sum>
[: 96: expr 1+1: bad number

Statistics calculated from raster map <Kyll_DGM_filled> and
uploaded to attribute table of vector map <Kyll_Pegel_EZGclean>.
Done.

the temp_file is still not removed from my mapset

The thing is, that the script added stepwise the columns. first the *_n, 
brek, then the next etc.
But now, it works, even with the error messages...

Thanks a lot!
