            Bug ID: 353509
           Summary: Crash after loading a full text entry as HTML page (as
                    a new tab )
           Product: akregator
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: web at markus.valtin.net

Application: akregator (5.0.1)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-12-generic x86_64
Distribution: Ubuntu Wily Werewolf (development branch)

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

Opening the HTML site of any RSS entry.
The side seemed to be loaded because I saw it for about a secound.
A SSL certificate validation dialog poped up before the application crashed,
but I think I tried also HTTP only sites.

If I restart the application, the application crashes again, because the tab
with the website is still open. I have to disconnect from the WLAN, start the
application again. Because there is no Internet, the site can not be loaded and
akregator does not crash. I have to close the tab to get the crashes to stop.


This bug report is actually for a crash after restoring the last session, were
I opened the full text HTML entry.

Right after the crash the following error appeared on the termial:
