blogilo (1.1) on KDE Platform 4.14.6 using Qt 4.8.6

Maybe a null reference on setting the user agent of http request.

New crash information added by DrKonqi

blogilo (1.1) on KDE Platform 4.14.7 using Qt 4.8.6

- What I was doing when the application crashed:
I entered my blogger details and hit "autoconfig" and it crashed.
Then I tried a completely manual setup and when I request the list of posts ... it crashes
