[QGIS-Developer] Split feature after dissolve

[Matteo Ghetta]

Hi devs,

maybe a silly question, but after a dissolve of a line layer, when using 
the split feature function to split the layer, instead of splitting in 2 
parts, the tool is splitting in n parts (where n = 113). Apparently the 
parts are randomly located.

It doesn't matter if the layer is shapefile, geopackage, temporary 
layer, postgis, etc.

Any idea why this is happening?

Cheers and thanks for any suggestion!

Matteo
