 I've encountered a bug when viewing a line string layer which causes a
 large portion of the map canvas to be covered with the line colour when
 zoomed to a specific view.  The data appears normallty when zooming in or
 out, or otherwise changing the canvas/view relationship.

 I've attached a png screenshot and a zip file containing the QGIS project
 and spatialite database.  Because the bug depends on the canvas size you
 may not be able to replicate immediately from this dataset.  You should be
 able to infer the map canvas size from the screen shot.

 This could be related to ticket 2915, which demonstrates a glitch plotting
 polygons.
