Hi all!

Please, can you help me how to debug this problem? When I'm copying or moving many files (I tried today to move 32 files from one folder to another in the same partition), the taskbar freezes and I cannot click on the buttons to switch applications. The desktop keeps working though because I can change windows with Alt+Tab. The taskbar and menus keep frozen for a long time, 10 minutes or more, depending on the number of files I move. Once I tried moving 400 files and it froze for an hour
Notifications are also frozen, and programs that show notifications get frozen as well.

In the logs (I'm using Fedora 25), when I move the files, I get many messages like these:

Code: Select all

The log gets flooded with these messages until the operation is completed.
Here are some specs:

I'm running Fedora 25, Kernel 4.13.16-100.fc25.x86_64

Hope you can help me!
Thanks!
