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
/usr/share/icons/hicolor/index.theme.
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
biggie.
