Videoporama 0.8.0 will not open or save project files with non-ASCII characters in the path

Binary package hint: videoporama

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu.

~> lsb_release -rd
Description: Ubuntu 10.04.1 LTS
Release: 10.04

2) The version of the package you are using, via 'apt-cache policy packagename' or by checking in Synaptic.

~> apt-cache policy videoporama
videoporama:
  Installed: 0.8.0-0ubuntu1
  Candidate: 0.8.0-0ubuntu1
  Version table:
 *** 0.8.0-0ubuntu1 0
        100 /var/lib/dpkg/status
     0.7.6-0ubuntu3 0
        500 http://us.archive.ubuntu.com/ubuntu/ lucid/universe Packages

3) What you expected to happen

Videoporama successfully opens and saves project files that contain non-ASCII characters such as á, ¡, and ñ as part of the file name or directory path.

4) What happened instead

Videoporama silently fails to open or save the file if the file name or directory path contains non-ASCII characters. Here are some examples of failing file names and directory paths:

/home/user/dir_a/file_á.idv
/home/user/dir_á/file_a.idv
/home/user/dir_á/file_á.idv

There is an exception: Videoporama will save a project file that contains non-ASCII characters if the ".idv" extension is left off the file name. Videoporama automatically adds the .idv extension when it saves the file. However, it will not reopen the file unless the file is renamed to remove all non-ASCII characters.

Note: I installed the Videoporama 0.8.0 package from Ubuntu Maverick while debugging the problem described in bug #629930. I also tried installing the latest version directly from the Videoporama web site, http://download.tuxfamily.org/videoporama/deb_pkg/videoporama_0.8.0_all.deb, and it has the same problem described in this bug report. Apparently since I installed a Maverick package on Lucid, apport-cli and ubuntu-bug refused to file a bug for this package.
