OS:                Linux
Installed from:    Debian testing/unstable Packages

I had two tabs open, one for local files and the second for an sftp connection.  I had the SFTP tab active and I double-clicked the tab area to add a new tab, and Dolphin crashed.

Application: Dolphin (dolphin), signal: Segmentation fault
