This is a bug tha will be fixed soon in a bugfix release. Its already fixed in git.
Hi Simon,
Which commit fixed this issue?

This is fixed in the 2.1.x bugfix branch. Commit id is 7154e51ff225d7521120b57e9acf77d52793b3a7

I'd appreciate if you can fix it in bugfix release, otherwise I'll apply the fix manually for my project.

The release is already prepared. I'll try to find the time to publish it soon.

Simon
