Bulk Deactivate Fails With Error

I see that on occasion when deactivating multiple plugins at once, with various plugins from other people as well. Probably one or more plugins has some older deactivation code or outdated nonce check. I would need to search through all my plugins to see if I can recreate and figure out which one is causing the issue and why (if it’s something that can be consistently reproduced).

However, it does not affect any of the regular operation of the plugins, and you can always deactivate the plugins quickly one at a time with the text deactivate link below each plugin on the plugins page, so not really a major issue.
