Problem with MP4 model when using two pass encoding

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Choose a video
2. Choose the profil : H.264 in MP4(4:3)
3. Activate the two pass encoding
4. Convert

What is the expected output? What do you see instead?
There is an error message : "Unable to find a suitable output format for
'/dev/null'".

What version of the product are you using? On what operating system?
I use WinFF 0.42 on Ubuntu.

Please provide any additional information below.
I solve this problem by adding "-f mp4" in the command line. I think other
model are affected, and it's not easy for beginner to solve this issue.
