Problem printing with gimp-print 5.0 and kde 3.2

[Marco Mennella]

Previously i print with cups 1.20 + gimp-print 5.0 alpha + kde 3.1.4 on 
my Epson C64. Now i've update my gentoo linux with kde 3.2.0 and when i 
try to add/configuring my printer in the same way i do with kde 3.1.4, i 
notice a problem with kde cups configuration module. The error reported 
is about problem in parsing my PPD file.
Is this a bug of new kde 3.2.0 PPD parser? If i downgrade to gimp-print 
4.2.6 the ppd problem there isn't, but i lost a lot of new feature 
included in new driver.
There is a method to override this?
Thanks
