Hi all,

build Emacs with commit

  Prefer make_formatted_string in svg_load_image
  commit c50e8c24247eb69d85b004a72197e710c8e1e32a

and then:

  • emacs -Q
  • M-x global-tab-line-mode RET

which gives me (line breaks added for better legibility):

  Error during redisplay: (eval (tab-line-format) t) signaled
  (error "Invalid format operation %06X; fill: currentColor;\"
   width=\"%d\" height=\"%d\" preserveAspectRatio=\"none\"
   viewBox=\"0 0 %f %f\"><rect width=\"100%%\" height=\"100%%\"
   fill=\"#%06X\"/><xi:include
   href=\"data:image/svg+xml;base64,%s\"></xi:include></svg>")

Best, Arash
