With the last git I can no longer see the png. Both in resources and timeline are not seen. In the terminal I have the following messages: Cinelerra Infinity - built: Dec 2 2020 10:36:34 git://git.cinelerra-gg.org/goodguy/cinelerra.git (c) 2006-2019 Heroine Virtual Ltd. by Adam Williams 2007-2020 mods for Cinelerra-GG by W.P.Morrow aka goodguy Cinelerra is free software, covered by the GNU General Public License, and you are welcome to change it and/or distribute copies of it under certain conditions.

EDIT: the same problem with jpg. An animated gif works.
