Sentry Crash Report:

Description Peter C. Trenholme 2015-02-20 21:36:27 UTC

Application: ktraderclient5 (5.2.0)

Qt Version: 5.4.0
Operating System: Linux 3.20.0-0.rc0.git9.1.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Rawhide)"

-- Information about the crash:
- What I was doing when the application crashed: Opening a GoogleChrome Web browser

Note: I'm currently on a Fedora "Rawhide" system, using a fairly new KDE 4.14.4 release and QT 5.4.0, so I suspect this is just a development issue. But, since it wasn't yet in yor system . . .

The crash can be reproduced every time.

-- Backtrace:
Application: KTraderClient (ktraderclient5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Thanks for the report.
The backtrace is unfortunately not informative ("a global object in KF5Service crashed in the QObject destructor").

I have recently removed many global objects in KF5Service, so hopefully this is fixed.
