[GRASSLIST:941] qgis and grass "cannot read region"

[Pierluigi De Rosa]

Dear all grass users,

I have some problem when I run qgis from grass. I have this warning:

Cannot read current region: is invalid line 11: <top:   1>

so when I try to open a grass vector file qgis will crash.
I tried to check my grass region setting but It seem good
This below is my wind file

proj:       1

cols3:      1
rows3:      1

Can anyone help me about this question??
Thanks to all
