[cups.bugs] [HIGH] STR #1431: Invalid IPP response

[Jens Elkner]

[STR New]

If DefaultLanguage is not set in /etc/cups/cupsd.conf (i.e. commented out)
CUPS sends an invalid IPP response, which causes e.g. Java (verified for
all >= 1.4) to fail with java.lang.IndexOutOfBoundsException, since the
decoder relies on the fact, that a value is always prefixed with 2 bytes
(length of value). 

E.g.:
....
