[BUG]: RSS Guard Lite crash on attached images #1449

Open Neo-CTC opened 2 months ago

Neo-CTC commented 2 months ago

Brief description of the issue

When rapidly switching between articles with images RSS Guard Lite will crash if not given enough time to load the images in between. Standard RSS Guard does not seem to be affected.

How to reproduce the bug?

  1. Enable Display attachments directly in article in the settings
  2. Load a feed with images, e.g. https://www.astronomy.com/feed/?post_type=potd/
  3. Rapidly switch between articles either by clicking or keyboard keys

What was the expected result?

What actually happened?
