Subject: v.digit crashes with "X connection to localhost:10.0 broken" error

After having v.digit running for a couple of hours, digitizing several hundred
new points, all of a sudden the v.digit GUIs vanish and this error appears on
the console:

X connection to localhost:10.0 broken (explicit kill or server shutdown).
Monitor <x0>: Premature EOF
GRASS 6.1-cvs>

?!#$^#!!!!.

Started with standard DBF connection, v.digit -n bgcmd=1;2;3;4;...

dbf/ and vector/ directories both contain data.

try to salvage with v.build:

G61> v.build map=field_depths
WARNING: coor files of vector 'field_depths@map1' is
         larger than it should be (17835 bytes excess).
Building topology ...
615 primitives registered
Building areas:  100%
0 areas built
0 isles built
Attaching islands:
Attaching centroids:  100%
Topology was built.

Number of centroids :   0
Number of areas     :   0
Number of isles     :   0


but the "coor files of vector is larger than it should be" warning remains.
how to get rid of it and make things clean?

Everthing seems fine but the last entry is missing its attrs (ok since it
broke on "submit".


Running self-compiled on debian over tunneled X via ssh (100mbit TCP/IP
connection in same room) with some usleep()s thrown in to keep processor usage
under 100% and network traffic down to "busy" from "extreme".

The size is written to the coor when it is closed, obviously it is wrong 
if v.digit crashes. Currently there is no other way to rewrite the size 
except to open and close in v.digit (which schould be done anyway to 
check last changes).

Ok, the data all seems to be there (except for the submit that crashed)
so no big drama. As I am not working from a clean source tree or a
straight X connection there may be something else causing the fault so
I'll close this bug, but let it be noted that once upon a time v.digit
crashed when hitting submit, after digitizing 650 or so points
successfully.
