Here the qgis project to test this bug report: https://db.tt/4PVgTlwl
expand it into /tmp dir and try

Can you try changing from a pattern fill to a plain fill, and see if the error goes away?

[marcobra]

Yes, i know, without linear pattern fill i get no error...

[tomchadwin]

In the short term, I'm not sure we can do much better than to trap the error properly. I don't know if Leaflet supports a pattern fill. If it does, we will have to extract the pattern into a web-friendly image format (which tiles, obviously).

Any ideas on how to pursue this one are gratefully received.

[tomchadwin]

If we trap the error, we can just substitute a plain fill.

[marcobra]

Will be nice to manage this error in some way.
Catch the error, show to user a warning, "The pattern fill conversion isn't supported, so layer: NAME_OF_LAYER pattern will be converted to plain fill" and then convert.
