[GRASS-user] v.dissolve - is this a bug?

[Richard Chirgwin]

Hi,

In running v.dissolve within a script, I am getting an intermittent failure:

ERROR: key column must be integer or string

Here's the script spot that fails (but only sometimes)

v.db.addtable MAP
v.db.addcol MAP columns="Dissolve int"
v.db.update MAP column=Dissolve value=1
v.dissolve MAP output=DISSOLVE column=Dissolve

The killer is that it isn't reliable - sometimes it works, sometimes it 
fails, and I can't tell why!
