Comment 47 for bug 1509139

#34 not works in Linux Mint (the line 198 is not the same).

Also, I try with:
change lines #177 and #202 in the file /usr/bin/xdg-settings from

command="`grep -E "^Exec(\[[^]=]*])?=" "$file" | cut -d= -f 2- | first_word`"

to

command="`grep -E "^Exec(\[[^]=]*])?=" "$file" | cut -d= -f 2- | first_word | head -n 1`"

But also, not works in Linux Mint (18 KDE).
