Ahh, I missed the -f option. Thank you.
Trying it, it didn't show the specific file that failed, but did give
some more pointers to look for.

I found out that this message appears when a "QWebview" is started
(python module: pqHelp.py). This appears to be an HTML viewer which
uses exactly one icon (reload).
In the strace logfile there was one mention of opening
This file appears to just list all available icons.

As a last shot in the dark, i decided to run identify on all files
with "reload" in the name, but the output is similar for all files.

I guess I'd best leave it with that. It was a fun experiment, but alas
not entirely succesful. I got the application working for what I want
to use it for and will have to live with the warning message. No
