Sadly, the log files do not tell us much other than Plex Media Server crashed while trying to analyse either of those two images (both are listed in the logs right before the crash is caught and the report uploaded to our crash reporting service).
Without access to the files that we suspect are causing the scanner to crash, we won’t be able to reproduce the issue under a debugger, which would allow us to fix the issue.
There is one alternative you could try, and that is to manually update to our newer preview build here: Much faster (hopefully), smaller (mostly) and better PMS builds preview (1.14.0.391-7623e9224) which may resolve the issue due to newer compiling tools and updated libraries.
