[Qgis-user] qgis metis cannot open some grass datasets

[Patrick Giraudoux]

I have migrated from Metis to Mimas (1.3), the latter from the OSGEO 
repository and  the OSGEO4w installer, all under Windows XP. Most of the 
things goes well, including opening GRASS dataset, except that one of 
them can non longer be opened from Mimas:

"Impossible d'ouvrir le jeu de données GRASS. Le jeu de données est en 
cours d'utilisation" (Impossible to open the grass dataset. The data set 
is currently in use)

However, the dataset can still be opened from the earlier QGIS version 
or directly from GRASS without any trouble. I have tried to open a copy 
from Mimas with no result.

Any idea about what happens and a work around ?
