 Hello,

 I am running GRASS 6.4.0RC5 on Ubuntu Karmic.

 I have been given a Mapinfo .tab vector file (polygons of administrative
 divisions of the city of Istanbul). Although the units seem to be in
 meters, the layer does contain no projection information. After many days
 of trial/error, I was unable to find its projection so I finally decided
 to rectify it so that I can use it with other GIS layers (EPSG 23035).

 I first imported the layer into a XY location. I then created a
 georeferenced location (EPSG 23035) and started GRASS in it. When I start
 the georectifier, it all seems OK (except the fact that I had to first set
 the scale to 1:300,000,000 to be able to see the layer ;o(. any other way
 to zoom into that layer?) and I was able to set many GPCs. When it was
 time to go to bed, I saved the GCP's in a POINT file under the group I had
 created and went to bed. The next day, when I relaunch the georectifier
 under the same group, I get the following error :

 OverflowError : long int too large to convert to int

 And the unprojected layer never gets displayed. I cannot continue my work.
 Trying the georectification with the same GCPs yield the same error as
 well.

 Is this a bug?
 Let me know if I can furnish more info.

 Here is part of the output of ogrinfo -so :
 Had to open data source read-only.
 INFO: Open of `mahalle.tab'
       using driver `MapInfo File' successful.
 Layer name: mahalle

 Layer SRS WKT:

 Please find attached a gml extract of the dataset for your convenience. I
 was able to reproduce the error with this gml layer as well :

 ogr2ogr test.gml input.tab -f "GML" -where "fid in (1)"
