Bug 362861

Application: kfontinst (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-22-generic x86_64
Distribution: Ubuntu 16.04 LTS

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

I was installing some tipographic fonts (double click on the font-type file) and then, suddenly, the installer crashed. I was doing it this way instead of using the fonts manager systemsettings5 because it hangs when I try to install any font from it.

Note that font installer stands in the little window that says "Installing", and it never closes automatically as in KDE 4, forcing me to close the window manually.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Instalador de tipos de letra de KDE (kfontinst), signal: Segmentation fault
