There is not a menu named “filter”. Can you be more specific about what you are clicking on? A screenshot would be helpful.
That message in the log is information unrelated do your problem. There might be more clues if you share the entire log (this forum allows you to attach files).
Does the Filters panel show up for you?
Can you add a filter to a clip that is not in the timeline?
Is the crash specific to the one clip/file, or does it crash for all files?
Sorry, the menu item was “Filters”. However, I tried to reproduce the error and it is not happening. I will try and find the .mlt file that was causing it and post a screenshot later.
