Bug Description

For the last month, saving a file or printing a file from my browser or any other application, or even trying to quit the file browser without doing anything, causes the file dialog and the entire system to hang (become unresponsive) for several seconds.

Thank you for your bug report. That's not specific to nautilus then?
Could you add your 'journalctl -b 0' log after getting the issue?

Changed in nautilus (Ubuntu):
importance: Undecided → Low
status: New → Incomplete

Sorry, I suspect it's specific to whatever part of the OS supplies dialogues to save files, but I'm not sophisticated enough to know what that means.
Here's the journal:

Un-locking the screen/desktop now also takes much longer than it used to. After correctly entering the password or scanning a fingerprint, nothing happens for a long time, and then eventually the screen is unlocked. Could that be related?
