I still don’t know for sure what is going on here. Most likely we are 
overriding some other data when copying the image. To prevent this I made the 
pre conditions of the new code explicit. If these are not fulfilled no app icon 
for WindowMaker will be created. I also changed the code to only create this 
icon for WindowMake, that way less systems will be affected by this issue. 
Could you please try again on your Letux?
