what3words 1.0, QGIS 2.8.9-Wien on Linux 4.4.0-22-generic

Not reproducible with QGIS 2.8.9. Please provide information how to reproduce this issue

gubuntu commented 8 years ago

Just open QGIS :-) I'm getting this with 2.8.9 26c3ece locally built on Ubuntu Xenial and 2.10.1 48d9afe but not 2.12, 2.14 or master.

Not reproducible on Windows and Linux. Please check that you have no Processing plugin installed in your user directory

gubuntu commented 8 years ago

A-ha, that's the issue, I have Processing installed but see it's not enabled in 2.8 or 2.10 because

This plugin is incompatible with this version of QGIS Plugin designed for QGIS 2.12 - 2.99

Surely all plugins (especially Processing) should not break with any version of 2? I've created https://hub.qgis.org/issues/14993
