Comment 4 for bug 1534963

I'm experiencing the same for Xubuntu 15.10 on a Surface Pro 3

uptime
> 09:59:00 up 7 days, 19:29, 6 users, load average: 0.12, 0.26, 0.24

So after 7 days the process

- RSS is 1187 megabytes

I've attached the result of
apport-cli -f -p <package name> --save bug.apport
(after killing the plugin)

I've also found a debian bug report similar to this:
