Bug 273538

Application: dolphin (1.6.1)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

Selecting two files from my local computer, I clicked and dragged them to another Dolphin window which had a sftp connection open. When I selected the "Copy files" option from the popup menu, it crashed.
However, between the time releasing the files into the new directory and for that popup menu to popup. I clicked and dragged the same files on my local computer into their same directory. The popup menu popped up at roughly the same time as the one from the sftp window and it was left open when I clicked the "Copy files" option from the sftp window.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
