Gmenu2x has a feature of associating icons to the filename. So for 
example, if your program's executable is called foo.dge, gmenu2x 
looks for an icon file foo.png in the same dir. If it finds it, it 
sets it as an icon. It works like that with joyrider's gmenu2x build 
for dingux and I also believe it works like that with my original 
gmenu2x build for the nanonote. However with GIT build, this feature 
is missing/not working. I also noticed that you can't set a custom 
icon via gmenu2x gui dialog, so that might be also related.
The only way to make icons work with the current GIT version is to 
manually edit the config for each entry and add the ICON= line.
