DuplicateOptionError when there is { in entry_points.txt file

[MikeFalowski]

I'm trying to build application with dependencies on taurus https://gitlab.com/taurus-org/taurus but it returns error.

It seems that configparser has problem with reading parameter starting with {

entry_points.txt file:
