[gthumb-list] gthumb missing plugins in debian

[Jackson Doak <noskcaj ubuntu com>]

I have just take over maintenance of gthumb in debian and ubuntu, but my new .deb is missing the following files

-rw-r--r-- root/root /usr/lib/gthumb/extensions/23hq.extension
-rw-r--r-- root/root /usr/lib/gthumb/extensions/facebook.extension
-rw-r--r-- root/root /usr/lib/gthumb/extensions/flicker.extension
-rw-r--r-- root/root /usr/lib/gthumb/extensions/flicker_utils.extension
-rw-r--r-- root/root /usr/lib/gthumb/extensions/lib23hq.so
-rw-r--r-- root/root /usr/lib/gthumb/extensions/libfacebook.so
-rw-r--r-- root/root /usr/lib/gthumb/extensions/libflicker.so
-rw-r--r-- root/root /usr/lib/gthumb/extensions/libflicker_utils.so
-rw-r--r-- root/root /usr/lib/gthumb/extensions/liboauth.so
-rw-r--r-- root/root /usr/lib/gthumb/extensions/libphotobucket.so
-rw-r--r-- root/root /usr/lib/gthumb/extensions/libpicasaweb.so
-rw-r--r-- root/root /usr/lib/gthumb/extensions/libpixbuf_savers.so
-rw-r--r-- root/root /usr/lib/gthumb/extensions/oauth.extension
-rw-r--r-- root/root /usr/lib/gthumb/extensions/photobucket.extension
-rw-r--r-- root/root /usr/lib/gthumb/extensions/picasaweb.extension
-rw-r--r-- root/root /usr/lib/gthumb/extensions/pixbuf_savers.extension

Why would this be?
