the la files are not emptied from dependencies

In debian/ubuntu, it is required to purge the dependency list of .la files or to remove it:

$ lintian ubuntuone-client-gnome_1.7.1-0ubuntu1_i386.deb
E: ubuntuone-client-gnome: non-empty-dependency_libs-in-la-file usr/lib/gnome-settings-daemon-3.0/libubuntuone.la
E: ubuntuone-client-gnome: non-empty-dependency_libs-in-la-file usr/lib/nautilus/extensions-3.0/libnautilus-ubuntuone.la

$ lintian-info --tags non-empty-dependency_libs-in-la-file
E: non-empty-dependency_libs-in-la-file
N:
N: The dependency_libs field in the .la file has not been cleared. It has
N: long been a release goal to get rid of unneeded .la files and clearing
N: the dependency_libs field from the rest of them.
N:
N: A non-empty dependency_libs field will also stall the Multi-Arch
N: conversation.
N:
N: The .la file in itself may be useful, if the library is loaded
N: dynamically via libltdl.

I'm thus settings this to critical and reject the current binary package
