Description Jim Stewart 2017-04-13 00:08:47 UTC 
Application: korganizer (5.4.3)

Qt Version: 5.7.1
Frameworks Version: 5.33.0
Operating System: Linux 4.4.0-72-lowlatency x86_64
Distribution: KDE neon User Edition 5.9

-- Information about the crash:
- What I was doing when the application crashed:
changing the fonts on the second line of a to-do list. The first line has a large font and the next line was to have a smaller font with a different type face. 
This consistently crashes the application 

- Custom settings of the application:
To do list is being editing in "enhanced edit mode" with all the fancy edit tools :o)  and on a separate monitor from the main Korganizer window

The crash can be reproduced every time.

-- Backtrace:
Application: KOrganizer (korganizer), signal: Segmentation fault

Comment 1 Laurent Montel 2017-07-07 09:12:25 UTC 
Do you have still this bug ?
Could you explain me which component do you launch etc to reproduce this bug.
I don't understand "changing the fonts on the second line of a to-do list."
Comment 2 Jim Stewart 2017-07-07 09:23:38 UTC 
Yes I just rechecked and it still crashes:
1) start a new to-do
2) choose the "rich text" mode 
3) put in a few lines of text
4) start to change the fonts on those text lines (the original crash was when I changed the second of the two entered lines of text). 
5) my 're-test' showed that changing the fonts on any of those lines of text _could_ crash the app (not every time but, it is not hard to tigger)
