From 340c6cfb7224a49ee202c60912fbe09e244ba31f Mon Sep 17 00:00:00 2001 From: baude Date: Fri, 5 Apr 2019 09:27:30 -0500 Subject: Correct varlink pull panic when pulling a non-existent image via varlink, we had a panic because when we detected a pull error we sent the error over a channel but still tried to deduce the image id on a nil object.
