[Qgis-developer] Announcing raster-pipes-2 branch for testing

[Etienne Tourigny]

Noticed a few issues with the save dialog

1) "format" drop-down is empty
2) cannot select a new file
3) segfault when saving to an existing file
4) It would be nice to have that action in the legend contextual menu,
like for vector layers.

regards,
Etienne
