6833: Tolerate exceptions when loading images

[cimi]

This PR fixes the crash reported in 6833 by returning null in case there's an error reading UI images.

During manual testing I noticed that the icon for Method Profiling can't be loaded on my system and this was causing the application to crash. I didn't find other resources with this problem.
