Perhaps Kaffe needs to be fixed instead, although it's no problem for us
to check for zero length arrays before fetching them (it's probably
faster, too).  

As for chars versus bytes, UIInfo was using char arrays to store byte
array information (xpm graphic data).  This usually worked because
graphic data tends to be word aligned, but its not very safe.  Since GTK
still uses 8-bit chars, I left everything string-related as byte arrays
when it gets close to a native call.
