Application: dolphin (14.12.3)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.16.7-21-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

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

With a file selected I right clicked on it to bring up the context menu for the file and then selected "Move to Trash" dolphin then crashed and I was presented with the bug reporter.

Other information that may be helpful is that I am currently running plasma5-session as my desktop now.

This does not occur every time.

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