[QGIS-Developer] Length measurement weirdness (again)

[Paolo Cavallini]

Hi all,
the measurements of a EPSG:4326 line appear correct in any SRS, both
with the interactive info tool and writing on the table the value of
$length, *if* the OTF reprojection is active (including 4326).
If it is not, the result is grossly overestimated (298 m instead of 228,
etc.).
Am I missing something, or this is a serious bug?
I attach a tiny sample showing the effect.
Thanks.
