Doesn't work with date filters

I'm trying to get date filters to work with this module but it just doesn't seem to work.

Reproduction steps:

1. Create a content type (A) with a date field.
2. Create a view with exposed filter of type 'between' on that date field.
3. Create another content type (B) with a field_embed_views field, using that view.
4. Create some test content (A) with different values for the date field.
5. Create a node of type (B) and set the filter to any range.

Expected result:
Filter is saved and limits view results to the range.

Actual result:
Filter is saved, but not shown in the edit form (B) and thus emptied again on save.
View shows items with a date value outside the range.
Viewing node B give an error:

( ! ) Fatal error: Cannot create references to/from string offsets nor overloaded objects in /includes/common.inc on line 6727

I did a lot of digging but I've become lost.
It appears to be that different date module functions are called when field_embed_views creates the filter and when views creates the filter.
