Description
>>> return tostring(require('lgi').cairo.PathData._field.header[3])
stdin:1: '__tostring' must return a string
stack traceback:
[C]: in function 'tostring'
stdin:1: in main chunk
[C]: in ?
>>> return getmetatable(require('lgi').cairo.PathData._field.header[3]):__tostring()
nil
And similarly for cairo.PathData._field.point. I got this error by attempting to perform a recursive dump on _G; I'm not sure where else it may come up.

Research direction
Start by reproducing the shown tostring call for cairo.PathData._field.header[3], then check the corresponding cairo.PathData._field.point case. Trace the Cairo binding code that creates these fields; done means both values have a valid string conversion instead of raising '__tostring' must return a string.
