Kernel error / Uwatec Smart via irda

I am trying to download dives from my Uwatec Smart Com on Ubuntu 14.10. 
I have tried to eliminate as much complexity and have downloaded the 
smart test app to gather info about the problem. In the below system 
log, I have captured the following actions:

 1. insert the usb irda dongle.
 2. run irattach irda0.
 3. run a quick irdadump to make sure the system sees the dive computer.
 4. run smart.

The following lines are output:

    DATETIME 2015-02-09T01:21:20Z (1423444880)
    VERSION 0.5.0-devel (61e9847196b4e7f4e2c80e47dd6cd7070c9c4418)
    uwatec_smart_device_open
    INFO: Discover: address=16c40100, name=Aladin Smart Com, charset=00,
    hints=8000
    INFO: Connect: address=16c40100, lsap=1

A few seconds later, a system error message pops up. The smart 
application never completes and can not be killed. The smart.log file is 
created, but nothing is ever written to it.

I have cloned the current git tree and compiled the app successfully but 
it generates the same error. I'm happy to help debug if you'd like.

Thanks!
