BUG SUMMARY

Loading.failed.mp4

Gladly I remember how this problem started:

1. Watch a video file from an external drive (Example: Why dogs like Puppy Linux.mp4).
2. Close the app and safely remove the drive.
3. Go to the File Manager's recent files -mine is Nautilus- and open that video (Why dogs like Puppy Linux.mp4) without any external drive connected. I must add that this was an accidental mistake because I want to open another file.
4. A Celluloid window emerged and obviously nothing was reproduced.

Since then... videos can't be played from the File Manager, but is possible to open them from Celluloid.
