The bug: in skin files, the "[editor]" section's "window-state-char" and
"window-close-char" (whose values, as the name implies, are single
characters) are parsed as color fg+bg+attr, and an ncurses/slang
colorpair is allocated for each.
The bug fix: move "window-state-char" and "window-close-char" keys from
"[editor]" section to "[widget-editor]" one.
