v.digit map creation weirdness on wingrass

[hamish]

Hi,

in the latest wingrass nightly build (r40876), but also seen before, when I make a new map with v.digit when I go to close the map everything sings along but then I get this error message at the end of the output:

Region restored to original extent.
Building topology for vector map <(null)>...
Registering Primatives...
Unable to read vector map

It's the same if I call v.digit (tcl) from the wxGUI menu, the gis.m menu, or "v.digit -n test' directly from the msys prompt with no module GUI. It's enough to start up with -n and exit intimately.

even weirder, when called from the gis.m menu/tcltk module GUI when the attribute From window should open I get an empty sqlite DOS box opening on top of everything and the tall&thin Form window stays all grey and unusable.

(apparently at some point I switched the mapset to use sqlite as the backend)

but I see the same (null) in the output even if I switch db.connect back to use dbf.

see discussion and DEBUG log in the second half of #843.

it seems to be losing contents of &Map by the time it gets to end() in centre.c.

tested with r42829 (self compiled WinGrass65 in a WinVista?32-box):

a loose translation of the message:

...
create topology for the vector map <(null)>
register primitives
vector map can't be read.

It gets there twice, the second time the vector has already been closed and is no longer available:

A bit annoying, but there is no report that the changes have not been saved, IOW, the module produces results as expected. Downgrading priority.
