Description RJVB 2016-02-10 14:18:14 UTC

Application: kontact (4.13.3)
KDE Platform Version: 4.14.14 (Compiled from sources)
Qt Version: 4.8.7
Operating System: Linux 3.14.59-ck1-mainline-amdf10-rjvb x86_64
Distribution: Ubuntu 14.04.3 LTS

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

1) started knode --nofork from a terminal
2) started kontact --nofork from a terminal

worked for a while, then quit knode as it became stuck trying to update my subscribed newsgroups

3) restarted knode --nofork from a terminal

after noticing that opened knode in the running kontact process, I went to the Kontact settings and deactivated knode.

Some time after that, this crash occurred.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault

Comment 1 Laurent Montel 2016-02-10 17:47:04 UTC

KNode was removed in kf5.
So it will not fix.
Sorry.

Comment 2 RJVB 2016-02-10 17:57:36 UTC

No more Usenet reader in KF5 PIM?

If  so, that's a perfect reason not to bother with it ...

Comment 3 Laurent Montel 2016-02-11 05:41:04 UTC

nope.
It was not ported to qt4 pure, it was not maintain, so it was removed for kf5.
