I am having this issue with Kubuntu 14.04 and the latest supported Linux kernel as of april 2016:
$ uname -rvi
4.2.0-35-generic #40~14.04.1-Ubuntu SMP Fri Mar 18 16:37:35 UTC 2016 x86_64
Only there were no multiple instances of gvfsd. Killing all gvfsd processes does not help. This Kubuntu was not an upgrade, but a fresh install. I did upgrade the kernels though with the latest "Hardware Enablement Packs".
