Crash on converted files

[arthurmougin]

Hello,
I am using France osm.pbf I got from geofabric and converted it into a .osm with osmconvert (The file size is surprisingly only around 200Mo).
When loading the file inside the program, it crash and display this message :

Traceback (most recent call last):
