I am exporting a small extract from OSM. I load the lines(layer 1) into QGIS and apply the function Explode lines. I get the error:

Algorithm Explode lines starting...
__len__() should return >= 0 See log for more details

Can anybody reproduce that? Is there a workaround that?


I think you are encountering this known issue: Bug report #10000 Cannot use osm layers (no features?)

You'll have to save to a different file format before you can use the data with Processing.
