Did you add a human readable error message for failed LAMS file import ? Maybe you also should even go a step further and say things like:
- this is a corrupt zip file
- this is a LAMS/LD zip and that we can't read currently
- this is a zip file that comes from another planet ....

My case was a student exporting a sequence to IMS LD in a local PC install and then trying to import it on our server via Moodle.

In LAMS 2.1 RC1, we got this kind of JAVA trace (only 2 lines shown). Easy to understand for me, but typical teachers won't.
