Bug#342378: file-roller: Sets incorrect passwords on .zip

Package: file-roller
Version: 2.10.4-2
Severity: important

File-roller seems to incorrectly set passwords on .zip files.

While I can set a password using file-roller and create a password protected 
archive just fine, and can also extract files from this archive fine using 
file-roller (after restarting the application), it is impossible to use the 
InfoZip unzip CLI as contained in the 'unzip' Debian package (v5.52-5) to 
decrypt this archive using the password previously set in file-roller. 

This only happens with some passwords. While 'foobah' will work fine, 
'foo$bah' does not, i.e. an archive garbled with this password can only be
restored by file-roller, but not using the CLI. 

My guess is that file-roller incorrectly passes the password to the zip 
utility, using something like 
  $ zip -P mypassword my.zip file1 file2

While this could be considered a security issue by itself (using the -e 
option to pass the password to the (un)zip application is highly 
recommended), the password may not be correctly escaped when being passed.

Obviously, passing a password value of 'foo$bah' using something like
  $ zip -P foo$bah my.zip file1 file2
will not work.

But as said before, this is just a guess and the problem may be caused by 
something completely different.
