No, unfortunately this is not a typo. Following is the status window in an
example. The scene contains a blob with 1500 elements (spheres) a disc and a
sky_sphere.
The blob is highly transparent with ior (1.1 in this case).
Negative values appear when the output image is ~800x600 and the antialiasing is
on and there are transparent objects (as far I've seen).

The memory cache it rate is extremely low, try to increase the cache size!
To do so go to the Edit menu and enter the Preferences dialog. The setting
is in the General pane.
