kcrash backtrace 1 (KF 6.21.0, Dolphin 25.12.0)

# SUMMARY
Dolphin freezes ("not responding") after creating a directory.
The directory is created on disk and visible in other windows, but the view of the creating window has not updated yet.

I simply had to terminate the application after it never recovered.

# STEPS TO REPRODUCE
I am unsure how to reproduce this bug. However, I have had it happen twice already.

Dolphin Version: 25.12.0

kcrash backtrace 2 (KF 6.21.0, Dolphin 25.12.0)
Comment 2 towe 2026-01-03 13:13:10 UTC 
I can confirm the same behavior. When creating a new folder (right-click --> new folder), the folder is created but no longer read. Instead, Dolphin freezes. Other Dolphin windows display the folder.

The problem does not always occur immediately. Sometimes folders can be created with Dolphin without any problems, but then suddenly Dolphin freezes when creating a folder.

This makes Dolphin 25.12.0 unusable for productive work.

The problem occurs on all my machines since Dolphin 25.12.0.

I use openSUSE Tumbleweed. The only workaround is to use an older Tumbleweed snapshot with Dolphin 25.08.3.
Comment 3 kp 2026-01-04 22:22:54 UTC 
Same problem on EndeavourOS. Dolphin Version 25.12.0.

Comment 6 TraceyC 2026-01-05 22:57:34 UTC 
Thank you for the bug report. Based on the backtrace this looks like a duplicate of bug 513345. This is fixed in Dolphin version 25.12.1. The fix will reach your system when it updates to that version.
