Application: kdeinit5 (3.0.1)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-22-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
I tried to make "apt-get install ttf-mscorefonts-installer". After some of 403 errors while wget tried to download fonts like arial32.exe and etc., app is crashed.

The crash can be reproduced sometimes.
