Description Jose Da Silva 2017-04-18 04:18:26 UTC

Application: konqueror (4.14.25)
KDE Platform Version: 4.14.30
Qt Version: 4.8.7
Operating System: Linux 4.10.9-200.fc25.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Typed URL into URL space, and webpage got partially loaded, then crashed.
Suspect a bad gif, jpg, or flash causes problem, since a fresh restart with new ads no longer triggers segfault.

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".

Comment 2 Jose Da Silva 2020-12-25 23:27:59 UTC

Created attachment 134330 [details]
not sure what this is.

To be fair about this, it is not a success.
It is now a bug that can no longer be followed, repeated, or anyone want's to track.

Moving-on to trying Konquero 20.12.0, KDE 5.76.0, QT 5.15.2 and a sample website
https://ca.finance.yahoo.com/
I see several things not working like videos, symbols, and even non-sense text.
I've attached a sample nonsense text URL.
