tested with WinGRASS-7.0.SVN-r47463-1-Setup.exe
there are a few issues with v.dissolve
(1) db.tables in $GISDBASE/$LOCATION_NAME/$MAPSET/sqlite.db
db.tables --verbose EU27_Biogeo_June08 bgr58fus br05exploded br05explodedl1 (Sat Aug 06 22:18:19 2011) Command finished (0 sec)

(3) v.dissolve from the wxgui

(5) and in the wingrass70-windows-commandline

there seems to be some issue with the sqlite-database

v.dissolve also silently fails on Linux as no effect is taken on the resulting map (also, one less area than in GRASS 6.4.svn):
North Carolina dataset:
GRASS 6.4.2svn (nc_spm_08):~ > v.dissolve zipcodes_wake out=zip_name Building topology for vector map <zip_names_10469>... Registering primitives... 206 primitives registered 14517 vertices registered Building areas... 100% 48 areas built 2 isles built Attaching islands... 100% Attaching centroids... 100% Number of nodes: 160 Number of primitives: 206 Number of points: 0 Number of lines: 0 Number of boundaries: 158 Number of centroids: 48 Number of areas: 48 Number of isles: 2 v.reclass complete. 48 features reclassed. Extracting features... Building topology for vector map <zip_names>... Registering primitives... 162 primitives registered 11115 vertices registered Building areas... 100% 27 areas built 2 isles built Attaching islands... 100% Attaching centroids... 100% Number of nodes: 137 Number of primitives: 162 Number of points: 0 Number of lines: 0 Number of boundaries: 114 Number of centroids: 48 Number of areas: 27 Number of isles: 2 Number of duplicate centroids: 21 Writing attributes... v.extract complete. Removing duplicate centroids... Building topology for vector map <zip_names>... Registering primitives... 141 primitives registered 11094 vertices registered Building areas... 100% 27 areas built 2 isles built Attaching islands... 100% Attaching centroids... 100% Number of nodes: 116 Number of primitives: 141 Number of points: 0 Number of lines: 0 Number of boundaries: 114 Number of centroids: 27 Number of areas: 27 Number of isles: 2
-> 48 areas reduced to 27 areas, look ok but:
GRASS 7.0.svn (nc_spm_08@grass70):~ > v.dissolve myzipcodes_wake out=zip_name Extracting features... 100% Building topology for vector map <zip_name@grass70>... Registering primitives... 205 primitives registered 14515 vertices registered Building areas... 100% 47 areas built 2 isles built Attaching islands... 100% Attaching centroids... 100% Number of nodes: 112 Number of primitives: 205 Number of points: 0 Number of lines: 0 Number of boundaries: 157 Number of centroids: 48 Number of areas: 47 Number of isles: 2 Number of duplicate centroids: 1 Writing attributes... Removing duplicate centroids... Building topology for vector map <zip_name@grass70>... Registering primitives... 204 primitives registered 14514 vertices registered Building areas... 100% 47 areas built 2 isles built Attaching islands... 100% Attaching centroids... 100% Number of nodes: 112 Number of primitives: 204 Number of points: 0 Number of lines: 0 Number of boundaries: 157 Number of centroids: 47 Number of areas: 47 Number of isles: 2
-> 47 (!) areas remain 47 areas

The bug is probably triggered by #548 (v.reclass + SQLite failure, but errors are suppressed in v.dissolve).

when you don't defined 'column' option, features are dissolved based on category. I have added warning about that in r59375.
North Carolina dataset:
> GRASS 6.4.2svn (nc_spm_08):~ > v.dissolve zipcodes_wake out=zip_name > Number of areas: 27 > Number of isles: 2
-> 48 areas reduced to 27 areas, look ok but:
this is probably typo I am getting 47 areas also in G6, you probably missed column=ZIPNAME. It seems to me that there is no difference in results produced in G6 or G7.
G6 & G7:
v.dissolve in=zipcodes_wake out=zip_names --o -> 47 v.dissolve in=zipcodes_wake out=zip_names --o column=ZIPNAME -> 27

also tested with WinGRASS-6.4.SVN-r47456-1-Setup.exe with the sql-db-backend:
I've tried the same in wingrass64 with dbf as db-backend, v.dissolve is working.
