[Qgis-developer] Problem with GDAL_translate. REST Services, QGIS

[Randal Hale]

Oh yeah - it was completely working. I haven't tried it since the 
upgrade to 2.2 on Ubuntu. That's why I ran through all the variations: 
windows/linux/etc to make sure it wasn't one thing vs something else. It 
seems ultimately to be a gdal thing since it failed on linux and 
windows. Linux was a bit more extreme with the segmentation fault.

Anyway - I'm hoping it's me - but I don't think so.....
