I subscribed to r/freeebooks via the Reddit spout. Currently, the update fails when cliupdate.php is executed via Cron or manually.

The relevant debug log:

[2019-05-14 11:38:37] selfoss.DEBUG: start insertion of new item "Newly Free Hobbies Kindle Book Lists for 2019-05-13"
[2019-05-14 11:38:37] selfoss.DEBUG: item content sanitized
[2019-05-14 11:43:42] selfoss.DEBUG: set cookie on rss.DOMAIN.com/ expiring in 2592000 seconds
[2019-05-14 11:43:42] selfoss.DEBUG: logged in using valid session
[2019-05-14 11:43:42] selfoss.DEBUG: Establish database connection

The last three lines keep repeating in the log, even after hours of script execution.

The issue also happens with a brand new database, after importing an OPML feed.

I am running PHP 7.3.5, on Arch Linux ARM, on a Raspberry Pi 3, using sqlite as the database.
