Você deve converter o caminho para o formato do Windows com cygpath -w antes de passá-lo para o chrome
/etc/mailcap
text/html; "/cygdrive/c/Program Files \(x86\)/Google/Chrome/Application/chrome.exe" 'cygpath -w %s'; needsterminal;
Não consigo abrir anexos em HTML no Chrome ao executar o Mutt on Cygwin. Eu visualizo a mensagem e, em seguida, entro na lista de anexos ( v ), depois escolho o text/html anexo e pressiono m para executar o tratamento do mailcap. A janela do Chrome é aberta com sucesso, mas nada está nela. Em vez disso, vejo a seguinte saída na janela do terminal:
