I can confirm this still exists in the Software Center when using xubuntu 14.04. See attachment for screen shot of the errors - in this case errors about object files.

This could cause serious problems on your computer. Please contact the person or organisation who provided this package file and include the details beneath." This is a known good package, the linitan errors are valid - but a deb should not have to comply with the latest policy standards to be able to be installed. Errors which should really be ignored: no-copyright-file dir-or-file-in-opt These two errors do not inherently make a package of bad quality. However, there should always be the ability to say, "No, i know better - please continue". Thanks.
