Sentry Crash Report:

Description Raúl 2011-10-03 19:50:48 UTC 
Application: konqueror (4.6.5 (4.6.5))
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.0.4 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:

I had konqueror opened for a while, I usually have lots of tabs and several windows opened. This is the third strange crash I have had in the latest days. These all were pointer and KJS related, but I couldn't figure out a common cause. Konqueror + KHTML has always been quite stable to me.

Please, let me know how I could focus this sparse bug report.

Regards,

The crash can be reproduced some of the time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault

Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond.

Thank you for helping us make KDE software even better for everyone!
Comment 2 Raúl 2018-10-30 23:10:02 UTC 
Hello:
Thanks for caring for this (way too) old bug. I don't think this report is useful anymore, last update was 7+ years ago and I'm not using konqueror anymore (unfortunately).
Moreover, I went on using konqueror as web browser some years more after latest update therefore I think the bug is not reproducible or solved.
HTH,
