Binary package hint: file-roller

Winzip and many other zip programs can now produce zip files that are protected by 256 AES encryption. FIle-roller in ubuntu cannot handle these zips. The files within the zips are shown fine but when you try and extract the following error occurs:

skipping: Test.txt unsupported compression method 99

I believe this is because "unzip" is used to extract the archive. This is the output from "unzip":
dbrewer@HCC122J:~/Desktop$ unzip Test.zip
Archive: Test.zip
   skipping: Test.txt unsupported compression method 99

If "7z" is used it works fine:
dbrewer@HCC122J:~/Desktop$ 7z x Test.zip

Extracting Test.txt

Everything is Ok

So I propose that file-roller uses "7z" instead of "unzip".

I attach an example of this kind of file. The password is "monkey" (no quotes).

Note peazip also can handle this. Maybe a replacement for file-roller?
