HMVC bug? CI_Exceptions is not working inside models

[eluser]CtheB[/eluser]
Hi All,

I tried to figure this out for hours, but i just can't come to a good solution.

Here is the Case:

- I've overridden the CI_Exceptions class: application/libraries/Exceptions.php
- I'm using HMVC for my modules.
- CI_Exceptions class works great inside:

* application/libraries/
* application/modules/controllers
* application/modules/views

- CI_Exceptions doesn't work inside:

* application/modules/models
* application/models

I'm using PHP v 5.2.6 with codeigniter 1.7.2 and HMVC 5.2.28

Anyone know's why this doesn't work? Is it a HMVC bug or a CI bug?

Thanks in advance. Let me know if you need more info. Let me also know if you have the same or another problem.
