- Status changed from Open to Closed
Fixed in revision faa3eb83 (SVN r14538). Note that the files uploaded here (provided by the original poster contain a layer (Luse) with one feature with invalid/problem-causing geometry. This will cause errors in the union no matter what, but the changes provided with faa3eb83 (SVN r14538) should address other issues, and should return more gracefully when invalid geometries are encountered.
Please test and re-open if required.
