Bug 355744

Application: digikam (4.12.0)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 4.2.0-17-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
The upload tool allows me to log into my account and select the available folders in SmugMug however as soon as I click upload to any of the folders I recieve a segfault and Digikam closes

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
