Wow!. 24 hr turn around from reported issue to fix. I didn't even  
have time to find example files.


...and this is typical of GRASS. Any commercial programs able to make  
this kind of claim?

Comment (by pkelly):

 It seems the problem was with gis_set.tcl not forwarding the warning
 message that g.proj emitted on to the user. I think I've fixed  
this now in

 SVN.

 This fix is for files that had no projection information  
associated with
 them. If there is a separate problem we can look at that too of  
course.

 Changeset 30557. http://trac.osgeo.org/grass/changeset/30557

Thanks Paul,

I'll see if I can track down a file that caused this kind of error.

Comment (by pkelly):

Hello Michael,
Please can you give an example of a file that causes this problem  
(put it
online somewhere and post a link?) and I will investigate it. As far  
as I
know any errors in parsing the projection information are reported.  
The

only thing I can think of is that the file doesn't actually contain
projection information - it's not an error to carry on creating a  
location
from this though, as some information from the file (i.e. the  
extents and

resolution) can still be used in creating the location.

AND... as far as I can see g.proj already outputs a warning when an
unprojected file is being used. Something like:
Read of file ./roads.shp was successful, but it did not contain
projection information. 'XY (unprojected)' will be used

An additional warning could I suppose be added if a location is being
created, specifically reminding the user of the need to run  
g.setproj or
g.proj at a later date, if we think that's necessary. But I really  
need to
see an example of the file that causes this problem as I can't see  
where

it would be happening.

Paul
