Bug ID: 357711
Summary: konqueror crashed -- session autosave related
[QPointer<KHTMLView>::operator->]
Product: konqueror
Version: unspecified
Platform: Debian unstable
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: konq-bugs@kde.org
Reporter: rasasi78@gmail.com
Application: konqueror (4.14.13)
KDE Platform Version: 4.14.14
Qt Version: 4.8.7
Operating System: Linux 4.3.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)
-- Information about the crash:
- What I was doing when the application crashed:
I opened konqueror from krunner. Iit restored a previously saved session. I
always kill konqueror so session is saved. The session is quite big with a ~15
tabs window and another singled tab window.
After the session was successfully restored konqueror "idled"* in the
background for some minutes and it crashed.
* I say idled but it actually takes some CPU as some opened webs require
javascript running in background
I have had some other similar crashed also related with autosave but
unfortunately I'm unable to explain how they are reproduced.
-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
