After:

# v.patch -e input="x75@cos90,x84@cos90,x85@cos90,x94@cos90,x95@cos90"
output="cos90_patch"

# v.clean input="cos90_patch@cos90" output="cos90_clean"
type="point,line,boundary,centroid,area" tool="break,snap,rmdupl,bpol"
thresh=0.01

# v.dissolve input=cos90_clean@cos90 output=cos90_diss column=LEG

...gives me this error:

DBMI-SQLite driver error:
Cannot step:
SQL logic error or missing database
ERROR: Unable to fetch data from table <cos90_clean>
ERROR: Unable to open vector map <cos90_diss_11516@cos90> on level 2.

Any idea?
I'm going to try the same operations with a postgres connection.

Yes, connecting to postgresql solved the problem.
