[Qgis-developer] error with grass-plugin

[G. Allegri]

Finally I've compiled my QGis from trunk, with self compiled grass
from trunk too, on Windows Vista.
qgis.exe seems to run fine, and I can load GRASS tools, the GRASS
shell (I've tried the famous g.proj -w and it runs perfectly). But
whenever I try to load a grass layer in QGis, this crashes with the
following warnings:

Any idea?
