Focus Point is stopping the deletion of some Matrix Fields

[MattWilcox]

I reported this to Pixel and Tonic but they've tracked the issue down to this plugin. When I try to delete some Matrix fields I get an Unknown Error thrown, and the fields can not be deleted.

Here's the mail I got back:

I see the error you're getting in your logs, though and it looks like the "FocusPointPlugin" is getting involved and causing the error:
