allow to initialize layer mask from color component
Submitted by wwp
Link to original bug (#587626)
Description
Please describe the problem: It is not possible to add a new layer mask based upon a channel. The checkbox is available, but the channel selection combo is not selectable (empty or disabled?).
Steps to reproduce:
- Open a RGB image (JPEG here)
- Layer >> Mask >> Add layer mask
- Select Channel
Actual results: You can't select any channel in the widget below.
Expected results: I expect I can select any of the R G B channels from the combo.
Does this happen every time? Seems yes.
Other information: It's gimp 2.6.6 from Fedora 10 x86.
Version: 2.6.6
