Reason why it was working in python 2 is because this file is added only when switched to python 3. Compare [logger.py](https://github.com/sugarlabs/sugar-toolkit-gtk3/blob/v0.95.2/src/sugar3/logger.py) file in sugar3 directory of v0.95.2 with [sugar directory](https://github.com/sugarlabs/sugar-toolkit-gtk3/tree/v0.95.1/src/sugar) of v0.95.1 |
