Not your fault, it is fixed now.
So I am not sure what to do about it.

I tried your vector pack file, and I have no problems displaying both
KOPER_NAAM and STRAATNAAM columns as labels on the map display. (On linux,
not Windows)

Sorry, I am new to GRASS and still have to learn a lot of the basics.
Still – great product that allows me to create maps that I need fairly
easily!
I have now run v.pack to create the vector file.
I am not entirely familiar with the projections, as I imported most data
from esri shapefiles and use X- and Y-coordinates in the Dutch RGD system
(basically meters easting and northing) I did not worry to much about the
projection (the region is small). If I run g.proj –p I get:

g.proj
-p
XY location (unprojected)
(Tue Aug 25 19:41:59 2015) Command finished (0 sec)
Basically it tells me I am using an unprojected mapset.
Hope this helps!

Dear Anna,
Thanks for your suggestions, I have tried the North Carolina dataset
(using the NAME attribute of the counties as label) and this indeed works
fine. I have also tried my original file, and there I still have problems.
The vector (polygon) files I wanted to label have been created from two
separate source files (imported from esri shape files) that I have merged.
During the merge I noted a number of problems with the polygons, although
it now displays OK. After this I joined the vector file with a new
attribute table. I can use that to color the polygons (create thematic
maps) but I cannot label the polygons even if I use the grass-generated
“cat”column.
I have tried not specifying a font at all (default) and then did specify a
font to see if that would help. Unfortunately not.
I have added the vector file (directory) as a zip file to this email.
Could you please use v.pack to send us the vector, you can't just take the
directory with the vector, the attribute data are stored separately and
v.pack takes care of that. Also which projection are you working in? Could
you send the EPSG? Thank you
Anna
Thanks for any further assistance!

Dear grass-users,
I am trying to put labels in a polygon layer, but the rendering fails. The

The command I use (through the GUI) is:
d.vect --quiet map=AlleKavels@GoesShape attribute_column=Kavel_nr width=1
font=romans label_color=black
Any suggestions?
Perhaps if you could replicate the problem on North Carolina sample
dataset or provide your vector file, it would help identify the problem.
Does it happen with other vectors or attribute columns? Have you tried
different font or not specify it at all?
