Well, I tried them both from console, and they worked. Yes, the -gtk
version has that annoying bug that shrinks the image. Anyway, it could be
superseded with the "overlap tiles" feature in josm. Better yet if I fix it :D

The problem is that the -gtk version outputs a fixed-size image of 2000x2000,
which generally is not the tile size at usual zoom levels. Instead, the -qt
version outputs the image at proper size:

$ webkit-image-qt
"http://josm.openstreetmap.de/wmsplugin/YahooDirect.html?bbox=12.5289968,37.6274879,12.6351747,37.7115329&srs=EPSG:4326&width=500&height=500"

$ webkit-image-gtk
"http://josm.openstreetmap.de/wmsplugin/YahooDirect.html?bbox=12.5289968,37.6274879,12.6351747,37.7115329&srs=EPSG:4326&width=500&height=500"
> foo_gtk.png

$ exiv2 foo_qt.png 
File name       : foo_qt.png
File size       : 99927 Bytes
MIME type       : image/jpeg
Image size      : 619 x 619
foo.png: No Exif data found in the file

$ exiv2 foo_gtk.png 
File name       : foo_gtk.png
File size       : 833574 Bytes
MIME type       : image/png
Image size      : 2000 x 2000
foo_gtk.png: No Exif data found in the file

I also agree I should recommend webkit-image-* from josm-plugins (or even josm,
I'd say -- one could always use the prebuilt wmsplugin.jar from the website).

I'm sorry if these binary packages weren't properly in shape, but I was in a
hurry uploading the -plugins corresponding to the new josm snapshot :). Having
packages uninstallable in sid isn't a good thing, so I decided to push these
webkit-image-* packages without waiting further, hope you'll forgive me ;)

Kindly,
David
