--- Comment #2 from Kevin Suo <suokunlong at 126.com> ---
I can reproduce this bug with the following steps:

1. Install cairosvg with pip.

2. start ipython interactive console:
> $ PYTHONPATH=/home/suokunlong/build/lo/master/instdir/program/ ipython3

3. Import cairosvg before importing uno:

> In [1]: import cairosvg                                                         
> In [2]: import uno
> In [4]: sys.modules["_elementtree"]                                             
> Out[4]: <module '_elementtree' from '/usr/lib64/python3.8/lib-dynload/_elementtree.cpython-38-x86_64-linux-gnu.so'>

4. Import cairosvg after importing uno:

> In [1]: import uno
> In [2]: import cairosvg
> AttributeError: 'NoneType' object has no attribute '__dict__'
> In [3]: import sys                                                              
> In [4]: sys.modules["_elementtree"]
> (None)

Fedora 32, master build as of today.
