Unfortunately you need to discuss this on gnupg side.

It is all Open Source software so if you provide a solution / script etc. that 
fixes this issue we will find a way to support it. The issue is known till 
several years now at least in Debian it is tracked (btw also others users 
using mutt+gnupg are hit by this):
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=888025

At least on a distribution level there are also other people trying to solve 
this.

Me personally was also hit by this issue several times and I would be more 
than happy if there would be a good solution ;)
