Short description of error
Blender crashes when trying to preview thumbnails in a folder containing dds/BC/s3tc compressed files. Without preview, it manages to load them and render correctly, but crashes at some point sooner or later.
It manages to corrupt blend files to not load at all/instacrash blender if those texture files are present/linked in the file.
Steps to Reproduce
Unzip the following file.
Load the .blend file.
Open the file browser, go to the tex->dds folder, and set the Display Mode set to Thumbnails.
