--- Comment #5 from Paul Vriens Paul.Vriens.Wine@gmail.com 2009-10-22 12:26:18 --- Patch is fine. None of those errors in the console and creating a dummy .skp file and double-clicking it launches Sketchup.
(Removed all wine related stuff from .local/share/applications and started with a fresh prefix).
