Not really sure to what component assign this ticket.
I was having a look to ticket #1993 and I noticed the following:
I created a new project and added a couple of layers, a world borders shape defined in wgs84, and a shape file of an European country, with a projected crs.
I then enabled otfr and selected as project crs the projected one.
While zooming out obviously the world border shape started to wrap (see attached screenshot), but suddenly qgis crashes. In the terminal I can see the following
Fatal: ASSERT: "std::abs( r_d ) > SMALL_NUM && std::abs( r_n ) > SMALL_NUM" in file /build/buildd/qgis-1.3.0/src/core/qgsclipper.h, line 270 Aborted
while this exercise cannot make a lot of sense, I think that qgis should not crash.
I noticed also that this happens with others projected crs but not all. For example if you use the world borders shape and one of the Alaska shapes of the sample dataset, qgis doesn't crash.
