Errors spotted when starting calibre in debug mode

Windows 10 and calibre v3.11.1 run from source...

I was doing some work on my plugins today and needed to test something in debug mode.

On calibre start up I saw 17 repeated occurrences of this warning:
Code:
libpng warning: iCCP: known incorrect sRGB profile
and immediately after the 'Started up in n.nn seconds with nnn books' message was this error:
Code:
Traceback (most recent call last):
  File "site-packages\calibre\gui2\cover_flow.py", line 145, in subtitle
  File "site-packages\calibre\gui2\cover_flow.py", line 105, in render_template
AttributeError: 'DatabaseImages' object has no attribute 'template_cache'
I don't believe either is related to anything I was testing. Do I need to worry about them?

The libpng warnings are probably from plugins loading icons. Someone in one of my plugin threads pointed out there was a problem with a few of the icons and supplied replacements. That reduced the errors a lot. I haven't gone looking to see which are causing the rest of the errors.

The libpng warning means some images used somewhere dont have correct srgb profiles and is perfectly harmless. The other error is a transient one at startup that should be fixed by https://github.com/kovidgoyal/calibr...ef79bb74555daf

OK. Thanks. A bit of googling showed me how to reduce the libpng warnings by fixing some of the icons in my plugins and config resources/images.
