[dev] [dmenu] doesnt open apps

[Jorge Ga]

OS: Debian 9 WM: i3
When i open dmenu (mod+d on i3) i can search any app, but when i try
to open, it just don't open.
I try to debug the commands using i3 debug mode but i'm kinda lost,
also i find on some arch linux post that maybe the fonts can be an
issue (i have custom fonts on debian) but i don't know if thats the
problem.
I have the same version of i3 and suckless tools on an Ubuntu machine
and works great.
I hope you can help me, i dont want to reinstall another distro.
