[Qgis-developer] plugin bug and patch - RGB composition plugin broken in 1.7.4 and master

[Etienne Tourigny]

The RGB composition plugin does not work (throws error below when
operation is requested)

The plugin has not homepage nor project page and is listed on the old
plugin page
http://pyqgis.org/repo/contributed

How does one submit bugs for these plugins, and how does one get them updated?

Here is a small patch that fixes the problem

Here is the error in 1.7.4 ( I get roughly the same in master)

An error has occured while executing Python code:
