[Qgis-developer] problem with QGIS 1.7 "--snapshot"?

[Tim Sutton]

Hi Jim

I'm guessing this is something to do with the new on the fly
reprojection support for rasters (the main difference between 1.6 and
1.7). I was able to replicate the issue here on the release-1_7_0
branch with all backported fixes applied. Under master branch, it
didnt even get as far as producing a snapshot. Could you file a ticket
for this? We will try to fix it for 1.7.1 9assign the ticket to me for
now).

Thanks

Tim
