Description Raúl 2010-09-16 22:35:24 UTC 
Application: konqueror (4.4.5 (KDE 4.4.5))
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.35.4 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
Hello:

I started a KDE sesssion where I had several(3) konqueror windows opened each one with several tabs(5-10). As it was after a forced reboot, the konqueror automatic sesion saver openen even more duplicated window which I conveniently closed. Since I hadn't internet connectivity on startup I wanted to reload all the tabs, I pressed shift-F5. This usually worked and in fact work for 2 out of 3 of the windows, but konqueror crashed on the 3rd.

HTH, regards,

I came across the same crash as the original reporter explained. My bactrace is slightly different we I'd say it's the same problem.
Comment 2 Andrew Crouthamel 2018-10-29 22:26:05 UTC 
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 3 Raúl 2018-10-30 23:08:07 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,
Comment 4 Andrew Crouthamel 2018-10-31 03:34:37 UTC
