I was wrong here. mailcap(5):

So doubled backslashes (as in .desktop files) are correct.

What is wrong is lack of backslashes added before ";" and it is a bug.

grep Exec /usr/share/applications/emacsclient.desktop
Exec=sh -c "if [ -n \\"\\$*\\" ]; then exec emacsclient 
--alternate-editor= --display=\\"\\$DISPLAY\\" \\"\\$@\\"; else exec 
emacsclient --alternate-editor= --create-frame; fi" sh %F

should be converted to /etc/mailcap entry

application/x-shellscript; sh -c "if [ -n \\"\\$*\\" ]\; then exec 
emacsclient --alternate-editor= --display=\\"\\$DISPLAY\\" \\"\\$@\\"\; 
else exec emacsclient --alternate-editor= --create-frame\; fi" sh %s; 
test=test -n "$DISPLAY"
