I have a CSV file where one line looks like this:

Duration, user, lat-start, long-start, lat-end, long-end
298, Casual,38.9101,-77.0444,38.91554,-77.03818

Each row in the CSV has two points and I need to draw a line between those two points for each row.

How can I do this using QGIS 1.8.0?

I have tried using the delimited text file plug-in, but it just draws points and has no line option from what I can see.
