[konqueror] [Bug 360497] New: Konqueror crashes on dict.leo.org

[via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=360497

Bug ID: 360497
Summary: Konqueror crashes on dict.leo.org
Product: konqueror
Version: 4.14.2
Platform: Debian stable
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: konq-***@kde.org
Reporter: ***@gmail.com

Application: konqueror (4.14.2)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.3 (jessie)

-- Information about the crash:
I opened http://dict.leo.org in Konqueror, entered "abtreten" and pressed
Return. Konqueror crashed immediately. After further testing, it appears the
crash happens for any phrase entered. This is new behavior, however - wasn't
happening a few days ago. I'm not aware of any particular changes on my system
that might have triggered this. Rendering is set to WebKit as per default.

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I'm afraid I've stopped using KDE in the meantime and can't test the scenario
again.
