Description Lukáš Karas 2015-11-01 17:03:30 UTC 
Application: kontact (5.0.47 pre)
 (Compiled from sources)
Qt Version: 5.4.2
Operating System: Linux 4.2.5 x86_64
Distribution: Ubuntu 15.10

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

I just read news in Akregator, open web page in new tab (KHTMLPart) and then Akregator crashed. 
Opened web page: http://www.weeklyosm.eu/cz/archives/5148
It happens everytime.

Kdepim, KHTML and KIO are compiled form source code, 
my KHTML head dfc046ae9dbca696505ac37d1b5dd5456d65b5c7
kio head 2ce45131cd42128628ed756605676f40a68a87ae
kdepim head e1a7b7db11604f20177ad3207619e41aa44be643

The crash can be reproduced every time.

-- Backtrace:

I need the newsgroup associate to test it :)
Comment 2 Lukáš Karas 2015-11-02 08:18:21 UTC 
By newsgroup, did you mean RSS feed? It is http://www.weeklyosm.eu/cz/feed
Then, open article "týdeník 271" (2.10.2015) in new Akregator tab. After page load, move cursor over links on this page...
Comment 3 Denis Kurz 2017-06-23 20:22:13 UTC 
This bug has never been confirmed for a Kontact version that is based on KDE Frameworks, except possibly a Technology Preview version 5.0.x. Those versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the opportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it.

Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.
Comment 4 Lukáš Karas 2017-06-24 07:01:47 UTC 
Hi. I can't reproduce this bug any more (version 5.2.3). Closing it.
