Is this missing dependency-bug of Python3 in Kazam of Debian 8.5?

I tried to record the bug related to my typing but could not get Kazam work as root and as non-root, see following; I installed it by apt-get install kazam ffmpeg successfully but not properly because of the errors/warnings

I did as root apt-get update and apt-get upgrade after that and iterated again but the problem persists.

Debugging

I run kazam --debug and get

Testing GAD3R’s proposal

I run apt-get build-dep kazam successfully, then again kazam but get the similar warnings/errors still

/usr/lib/python3/dist-packages/kazam/app.py:145: Warning: value "((GtkIconSize) 32)" of type 'GtkIconSize' is invalid or out of range for property 'icon-size' of type 'GtkIconSize'

I think this may be the problem that Kazam wants python3 but I have python 2.7.9 (python --version gives Python 2.7.9), so there can be a missing dependency. How to proceed?

Hardware: Asus Zenbook UX303UA
OS: Debian 8.5
Linux kernel: 4.6 (backports’ one)
Graphics: modesetting and non-free package for skylake CPU support
