From https://bugs.launchpad.net/catfish-search/+bug/1590034 Catfish doesn't show icon of any search result (either in "compact list" or "thumbnail" mode) screenshot: http://i.imgur.com/PS2ey7E.png I'm on Arch Linux x86_64 with catfish-1.4.2-1
This is likely resolved with the upgraded thumbnailer and usage of icon standards. Can you try this again with catfish-git? https://git.xfce.org/apps/catfish/
Marking resolved based on user feedback.
