Right now, "select by radius" deselects an existing selection only, but doesn't select any new items. All other selection types seem to work.

I figured out the problem! It only occures when working on a geographic CRS, like WGS84! Sure, a circle on the canvas isn't a circle on ground on geographic map projections, but that doesn't make sense. A rectangle (for selection) on WGS84 also isn't a rectangle on ground :)

If a user wants to select a radial area on the canvas, he should also be able to do this on a geographic CRS. The selection isn't based on real map units, it's only a visual selection tool.

It works fine under Windows too.

I think it is a local problem. Feel free to upload your data and project. Otherwise it is difficult to replicate the issue.
