The latest version of XnView MP (and the previous versions) shows neither a thumbnail nor a preview picture in the browser. I can open and display the file. Here is the MediaInfo report for an example file:

The same applies to .MOV files.
Attached are two samples.

I just discovered that myself. See my comment to my bug report on AVI files and make "Show as thumbnail" the DEFAULT setting!
