After debian Update Bookmarks makes NC to hang

Hi guys,
Today I did an update to my debian VM. Just a few packages could be updated (see below). Now I appear perfomance issues with NC until a timeout of the complete NC.
It seems to be an issue with bookmarks. I added about 5 links to bookmarks and it was getting more worse. Favicons for the new bookmarks are not loaded or displayed. RIght now, when renaming a bookmark I cannot access anything anymore in NC. Without using bookmarks everything seems to work fine. I recently also updated vom NC19 to NC20. THe issue can only be solved by a reboot.
In the protocol center I only recognize quite a lot entries about debug on the apps:

Debug app /appinfo/app.php is deprecated, use \OCP\AppFramework\Bootstrap\IBootstrap on the application class instead.

Okay, it seems not to be an issue with the update.
I was able to delete the 5 entries in the db directly and now my system is back and running.

Bookmarks seems to have an issue with adding links like:

I already got links from in the list which are working, but the added entries won’t. The only thing I recognize while adding the link is that no favicon is loaded and the description does not make sense.
