Issue with .psd files and -dissolve operator

I was attempting to use the dissolve operator to do color watermarking and ran into an issue because my watermark image is a .psd file, apparently with 2 layers. If I run the command:
convert crest.psd crest.png
I get 2 files:
crest-0.png
crest-1.png
As far as I can tell, these files are identical. I don't have photoshop, to see if this image has layers myself. This crest.psd image is composited onto another image with no problems, the alpha component is handled correctly and everything looks good. But when I use the .psd file with the -dissolve operator, it doesn't work correctly.
composite -dissolve 20,100 crest-0.png bg.jpg dissolve_png_20.jpg
yields the image dissolved correctly on the green bg.jpg:
composite -dissolve 20,100 crest.psd bg.jpg dissolve_psd_20.jpg
yields the image incorrectly dissolved over the green background image:
Any ideas, besides telling the users to convert all their .psd files to .png files?

usually the first layer of the psd file is the image composed from merging all the layers, so just use it as image.psd[0]
rather than image.psd

composite -dissolve 20,100 crest.psd[0] bg.jpg dissolve_psd_20.jpg
gives an error "composite: No match."
I originally ran into this problem in a ruby script using rmagick, where I get the same results as the commands I posted earlier. Using rmagick I am getting the first image when I open the file. That image works fine for an overlay composite, but not for watermark and dissolve.

you should not be getting an error unless your psd file is corrupt. what do you get from identify -verbose on your psd file?
what version of IM are you using? if old, perhaps upgrade
Note you can now do
convert ... -compose disssolve -composite
see -compose

To update, other .psd files from that client do work fine with watermark and dissolve. Apparently something with this specific image is causing this problem.
