This was the code that caused the crash:

<pre>
import itertools
layer = iface.activeLayer()
feats = [ feat for feat in layer.getFeatures() ]
selected_feats = []
selected_feats.append(feats[0])
del feats[0]
k=0
while len(feats) !=0:
for i, feat in enumerate(feats):
d = selected_feats[k].geometry().distance(feat.geometry())
if d == 0:
selected_feats.append(feat)
k +=1
del feats[i]
lines = [ feat.geometry().asPolyline() for feat in selected_feats ]
epsg = layer.crs().postgisSrid()
uri = "LineString?crs=epsg:" + str(epsg) + "&field=id:integer""&index=yes"
mem_layer = QgsVectorLayer(uri,
'4testing_feats_ordered',
'memory')
prov = mem_layer.dataProvider()
feats = [ QgsFeature() for i in range(len(selected_feats)) ]
for i, feat in enumerate(feats):
feat.setAttributes([i])
feat.setGeometry(QgsGeometry.fromPolyline(lines[i]))
prov.addFeatures(feats)
QgsProject.instance().addMapLayer(mem_layer)
