Hi Nyall
I have one of several features in an ESRI FileGDB:
MultiLineStringZ ((706969.83589982986450195 6203593.05810022354125977
46.92369999999937136, 706955.03999996185302734 6203604.32000017166137695
47.05999999999767169, 706951.05999994277954102 6203607.34000015258789062
47.05000000000291038, 706949.42999982833862305 6203608.59999990463256836
47.03999999999359716, 706934.7797999382019043 6203619.71430015563964844
46.66000000000349246))
Running your python snippet gives the following result on the FileGDB:
-2147483643
Identify results on the FileGDB:
(Derived): (clicked coordinate X), (clicked coordinate Y), Length, Part
number, Parts, Feature id
Exporting the layer to SHAPE (in QGIS):
Running your python snippet gives the following result on the SHAPE: -2147483646
Identify results on the SHAPE:
(Derived): (clicked coordinate X), (clicked coordinate Y), Closest vertex
X, Closest vertex Y, Closest vertex Z, Closest vertex number, Length, Vertices,
feature id, firstX, firstY, lastX, lastY
So quite a difference between two (identical I hope) data sets.
The above is made in QGIS 2.18.14 x64, Windows 10.

This sounds odd to me - either the layer in QGIS has a Z value, or it
doesn't. Exporting to another format should not be adding z values
which QGIS could not read in other circumstances.
What do you get if you run:
[f.geometry().wkbType() for f in iface.activeLayer().getFeatures()][0]
in the Python console after selecting your geodatabase layer?
