Plugin Filter problem

[zsinx6]

Description

I'm having the following error when any filter is enabled (in this case the Smoothing Filter):
[Plugin:Error] Unable to construct object 'OpenTabletDriverPlugins.SmoothingFilter'

System Information:

Name	Value
Operating System	Arch Linux
Software Version	Build from master - AUR
Tablet	Gaomon S620

This plugin library gets updated with basically every release. I don't maintain it enough to keep it up to date with the master branch, so as soon as anything modifies how filters work, some plugins will break.

Then if I switch to the last release, will it work?

You're on cutting edge development builds right now, so in short for me to resolve this issue the plugin repository needs to be updated.
