7zip offers two ways to encrypt files: encrypt file contents only, or encrypt the header, making it impossible to see the list of files without the password.

Ark supports the first type properly, by prompting for a password when the user tries to extract a file.

However it fails with the second type, trying for a while (~1 min) to read the archive, then failing with a "Reading the archive xxx. failed with the error 'Incorrect password'.

Reproducible: Always

Steps to Reproduce:
1. Create archive with 7zip: 7z -ptoto -mhe=on a somefile.txt
2. Try to open it with ark.


Expected Results:  
It would be nice to have ark fully support these files, however, it should at least fail immediately with a "Ark doesn't support encrypted-header 7z files at the moment" type of error message.
