Version:           1.2.1 (using KDE 4.2.2)
OS:                Linux
Installed from:    Debian stable Packages

Fresh installation of Kubuntu 9.04 with fresh (today's) bug/security updates, no crashes nor file corruption. Went to "root" in Dolphin's "places" menu, then right-clicked the central pane (with the folders for bin, boot, cdrom, dev, etc, home, lib...), then clicked "properties" in the context-menu.  Afterward, I could just restart Dolphin (doesn't make the whole system hang, or make me reboot to re-start Dolphin), so I'd consider this pretty minor.

Got this crash info:

Application: Dolphin (dolphin), signal SIGABRT
