IQ crash on S60 but works in the simulator - troubleshooting recommendations?

My first app just got approved and released on Friday, WUradar Widget. Today I started getting some questions and one report of CIQ crash every time the widget is opened. The report is from S60 user using GCM-IOS version 3.22.

My development environment set up is:
Windows 7
eclipse 4.70
CIQ SDK 2.3.4

The user was able to send me the CIQ_LOG.TXT file and this is what I see.

ERROR: Invalid Value
DETAILS: failed inside handle_image_callback

Given the statement about image callback, I suspect this has something to do with the use of makeImageRequest method. I am at a loss on how to reproduce the issue to troubleshoot as I don't have neither a S60 nor an IOS device to confirm the results.

Any suggestions on where to start the troubleshooting?
