What I did:

• Downloaded the addon
• Clicked SIAC -> Import -> New
• Added a random PDF, titled it "Test", pressed Ctrl + Return
• Clicked SIAC -> Read First in Queue

Error message

Error
An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.
If the issue only occurs when add-ons are enabled, please use the Tools > Add-ons menu item to disable some add-ons and restart Anki, repeating until you discover the add-on that is causing the problem.
When you've discovered the add-on that is causing the problem, please report the issue on the add-on support site.

Additional info that might help

• I installed Anki from the official website, but can reproduce this problem in the version packaged in official repository (Manjaro)
• No other addons are currently enabled
• Running anki from console sends out this message: add-on should use methods on col.decks, not col.decks.decks dict

EDIT: I can open the pdf from the Queue Manager -> PDF notes -> Open

Thanks for the report, this will be fixed with the next update. Edit: update is up on Ankiweb

Installed update, instantly fixed the Read First button, improved performance on the PDF reader, and killed every mosquito in a 3 mile radius. Thank you!!

To be thorough: Launching from the console still gives me warning messages saying add-on should use methods on col.decks, not col.decks.decks dict, but it doesn't seem to affect anything.
