Hi all. Just got a crash: Fatal: ASSERT: "std::abs( r_d ) > SMALL_NUM && std::abs( r_n ) > SMALL_NUM" in file /home/paolo/build/qgis_unstable/src/core/qgsclipper.h, line 270 This happens when the reprojection on the fly is enabled and the Capture Orthogonal lines tool is activated. All the best. -- http://faunalia.it/pc
