I use linux mint 12 with the latest OS 1.4.2 and MLT from PPA (0.7.8), I do not use Gnome shell or unity.
I have a ghost clip, which is not visible on the timeline and only 3 frames long (25fps) and it is always visible on the preview video, even I put an other track and clip over it, doesn't matter.
I wrote ghost, because it is not possible to see, select, move, delete from the timeline and when I zoom in below 4sec, tracks and positioner are gone. Zoom out I got back.
I think, I made an unwanted action, cut or something like this and that cause this.
Here I wrote a version of this topic, because I think they should have something common: viewtopic.php?f=11&t=1226#p5797
Here is a log from console, when I zoom in:
/usr/lib/pymodules/python2.7/openshot/classes/sequences.py:779: GtkWarning: gdk_pixbuf_scale_simple: assertion `dest_width > 0' failed
new_pixbuf = pixbuf.scale_simple(remaining_pixels, height, gtk.gdk.INTERP_NEAREST)

I think, this is caused by this ghost clip.
I exported to xml, easy to see this clip and delete, but not possible to import the xml into openshot.
OSP file is not really human friendly and I failed to delete the relevant part.
Any idea, how to remove this clip manually from the project file?
