that might try to fix the missing layers. There's a default handler (QgsProjectBadLayerDefaultHandler) which simply ignores all missing layers. Then there's a GUI handler (QgsProjectBadLayerGuiHandler) in GUI library which asks user about the path for missing layers. QGIS application automatically installs the GUI handler on startup. This should allow python plugins/applications to work with QgsProject without a fear of a segfault as there are no more exceptions thrown during load/save of the project files. Some further notes: - removed QgsProjectBadLayerException class and (now empty) qgsexception.cpp file - openFilesRememberingFilter() moved to QgisGui namespace (was duplicated: QgisApp vs QgsOpenVectorLayerDialog) - removed deprecated buildVectorFilters_ methods - added python bindings for new classes/methods git-svn-id: http://svn.osgeo.org/qgis/trunk@12350 c8812cc2-4d05-0410-92ff-de0c093fc19c
