OK, this fails for me too. Thanks for reducing that testcase.<br>
<br>
I also spotted that therion had been binNMUed (read "rebuilt against the<br>
latest dependencies") so it is actually fully using PROJ 6.1.0.<br>
<br>
I'd guess this is probably a general incompatibility with newer PROJ.<br>
<br>
Cheers,<br>
