[Qgis-developer] Re: Display raster fails

[Luca Casagrande]

Hi guys!
I am currently working with latest SVN , but after the today sync ( i know 
that it's not a good way of work using the unstable edition, but bug-testing 
had to be done) i can't display raster anymore...
How can I use the previus SVN?

Thx
Luca
