I am trying to convert a few polygons to polylines so I can save them as a .GPX file.
I'm using QGIS 2.8.1 (Wein) on the Mac.
It seems to be hanging. I only have a few small polygons (see screenshot) but it's taking forever. I can't tell if it's actually processing them or if it's crashed. I usually give up after waiting 10-15 minutes.
Has anyone else run into this problem before?

EDIT: I found a workaround by using GDAL ogr2ogr in the Terminal to directly convert the shapefile to a .gpx file. I used this command:
ogr2ogr -f GPX -dsco GPX_USE_EXTENSIONS=YES FPS_buildings.gpx FPS_buildings.shp -nlt MULTILINESTRING
This is a good workaround but I still don't have an answer about my original question.
