Bug in HSB stack to RGB conversion?

[Gabriel Landini]

When I convert an HSB stack into a RGB Color image, the image cannot
"unzoomed" anymore (or closed).

opensuse linux 12.2 (64bit)
IJ 1.47d15 Oracle Java 1.6.0_35 or in OpenJDK 1.7.0_07

The console shows the messages below when trying to unzoom with the mangifying
lens tool.

Cheers
Gabriel

This v1.47d regression is fixed in the latest daily build (1.47d16).
