Steps to reproduce:
1. Enable auditing on a 3.4.6 instance and start the system;
2. Pick a file whose name doesn't contain number.
3. Show the file in preview and select show_audit.ftl: works fine (expected)
4. Edit the file name and add 1 in front:
Audit info are displayed
Audit info are displayed only for the file whose name does not contain numbers
The above applies to both content and spaces.
