Hi, sorry something happened with Evolution that I don't understand and it just sent the message quoted without my response. Should always stick to mutt. There's a bug in BuildRoot that prevents me testing right now, when you use LINUX_OVERRIDE_SRCDIR. BR developers are looking into that. I'll test this once there's a resolution for that. /Jarkko
