zip files fail when using international character sets

[teledyn]

this is the second time it has happened, this is a fresh install of Ubuntu 11.10 completely up to date with latest revisions.

the gui extraction unpacks only track 4 and the extra info files

using the unzip command line I see the files unpacked:

garym@strata:~/Music/incoming$ unzip /home/garym/Downloads/Happy_Birthday.zip
