I tried to open a .wmv file in Thunderbird. I was asked to download files in order to have it accessible. At the end of the installation
An error occurred - Location not found. error message displayed with just the OK button available. Now when I press the Play button just the error message displays so I am not sure which packages need to be installed/uninstalled.
I have installed Ubuntu 12.04 (32-bit) with open-jdk-7.
Error was generated when installing:
GStreamer ffmpeg video plugin
It seemed that it took a while to have the process completing all steps of the download / install before the error message displayed.
