     Hello,

     for me the scanimage code is perfectly correct. I don't think 
anything needs fixing in it. My "patch" is a workaround for a bug that 
comes from elsewhere.
So the ppa you built is working fine for you and failing for others ? 
Are glibc used different, or compiled with a different compiler ?
