I copied the 1.3.2. files over 1.3.1 today and everything's running fine.
Versioncheck, however, reports
Total files/folders checked: 214
Mandatory files missing: 74
Optional files missing: 138
Files left over from outdated version: 1
Outdated file versions: 0
spotchecking shows that the missing files are, indeed, on the server, accessible, and working.
This is a known bug with versioncheck on a subdomain.

Thanks.
FWIW, Coppermine is in the root of a virtual server
http://gallery.mydomain.com, where the real root is /var/www/html/gallery
Might your subdomain also be accessible as: http://www.mydomain.com/gallery ?
