Description Peter Lemken 2016-09-30 06:49:48 UTC 
Application: kontact (5.3.0 (QtWebEngine))

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.7.4-200.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

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

Starting kmail or kontact from konsole brought up this error of missing symbols. This is after an upgrade from Fedora 23 to 24, which went through without problems.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Christoph Feck 2018-12-20 18:53:57 UTC 
Crash is caused by dlopen library loader error, possibly because of a broken ldconfig setup. If this is reproducible with all packages updated from consistent repositories, please report this issue directly to the bug tracker of your distribution.
