I am attempting to re-project a vector shapefile from Natural Earth, following a qgis tutorial. Another user reported this error, but a solution has not yet been reported.
Given this post, and the last line of the error, I suspect that there is something wrong with the CRS setting, etc. Though, I have not been able to identify it.
Export to vector file failed. Error: Failed to transform a point while drawing a feature of type 'ne_10m_admin_0_map_units'. Writing stopped. (Exception: forward transform of (3.141593, -1.570796) PROJ.4: +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs +to +proj=merc +lon_0=0 +k=1 +x_0=0 +y_0=0 +ellps=WGS84 +datum=WGS84 +units=m +no_defs Error: tolerance condition error)
I am using qgis 1.8.0 on Ubuntu 12.05. Thanks for the help!
