[dromer]

Is the libpng in debian buster outdated or too new for veejay?

[gui-lux]

Old thread, but uninstall qrencode and related is a workaround.

[game-stop]

It's possible this is due to outdated libpng as it doesn't find a reference to png_create_write_struct. Perhaps, it picked up the wrong include file. I'll look into this as well.
