Bug ID: 299020
Severity: crash
Version: unspecified
Priority: NOR
Assignee: konq-bugs@kde.org
Summary: Konqueror crashes when switching to embedded KPart
Classification: Unclassified
OS: Linux
Reporter: kdedevel@etotheipiplusone.com
Hardware: Ubuntu Packages
Status: NEW
Component: general
Product: konqueror
Application: konqueror (4.8.2 (4.8.2))
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic-pae i686
Distribution: Ubuntu 12.04 LTS
-- Information about the crash:
Whenever Konqueror switches to an embedded KPart e.g. gwenview or okular, it
will crash with the attached backtrace.
For me, running:
konqueror http://www.google.co.uk/images/nav_logo_hp2.png
(which, with my config, will attempt to use the embedded gwenview KPart to view
the png file) will crash konqueror with 100% reproducibilty. Seems
superficially similar to Bug 265217; maybe adawit will have some insight into
it :)
The crash can be reproduced every time.
-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
