SUMMARY
Sometimes, when browsing a directory with dolphin after using the "Open as
Administrator" option to view root-owned folders, the dolphin window will
freeze and become unresponsive. After a short while, the window is killed. This
happened while I was browsing the /boot directory. I saw this in journalctl
both times it happened:

I had this happen twice very quickly, and then when I went to repro it a third
time to gather more information I couldn't get it to happen, so it's not 100%
consistent.
STEPS TO REPRODUCE
1. Navigate to /boot in dolphin
2. Right-click and select "Open as Administrator"
3. Enter password
4. Browse the directory and subdirectories. Click on files. Interact with the
window.
OBSERVED RESULT
Sometimes, the window will freeze and no longer respond to input. Eventually,
it will be killed.
EXPECTED RESULT
Expected that the window will not freeze when browsing the directory.
