Application: dolphin (4.14.13)
KDE Platform Version: 4.14.13 (Compiled from sources)
Qt Version: 4.8.6
Operating System: Linux 4.2.0-35-generic x86_64
Distribution: Ubuntu 14.04.4 LTS

-- Information about the crash:
I was trying to open a recently changed file from within the dropbox menu that appears with the icon in the tray. It typically opens the folder in which the form is saved. Dolphin crashes while it is being opened. Otherwise I do not have problems with dropbox or dolphin, except that I need to open dropbox from the terminal with DBUS_SESSION_BUS_ADRESS="" dropbox start in order for the icon to appear.

The crash can be reproduced every time.
