When I used "Line Intersection" tool, I got the following error message.

An error has occured while executing Python code:

Traceback (most recent call last):
  File "C:\\OSGeo4W\\apps\\qgis-dev\\python\\plugins\\fTools\\tools\\doIntersectLines.py", line 96, in accept

  File "C:\\OSGeo4W\\apps\\qgis-dev\\python\\plugins\\fTools\\tools\\doIntersectLines.py", line 169, in compute
    outFeat.setAttribute(0, v1)
KeyError: '0'

Please, see issue #16157.

There is a hack that solves the problem (for simplest case tested for me).

provider1.select(allAttrs)
while provider1.nextFeature(inFeat):
