empty.xpm
Obviously empty.xpm is a solution.
A similar solution would be to 'empty' the original /home/tc/.logo.xpm file.
Both isn't trivial, as just creating a 0-Byte-File doesn't work.
Seemingly you have to create a real 'xpm' file faking kind of zero content.
I used gimp to create an 1x1 pixel image with the same #4f5f82 color
used by /home/tc/.setbackground and stored the result in xpm format as empty.xpm.
