Description David 2011-03-07 18:13:35 UTC

Application: rekonq (0.6.1)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I noticed since sometime that firefox (amd64) has problems with 
the flash player 10.3 preview (64 bits)
rekonq uses the nspluginwrapper and flash 10.2 (32bits) 
but both show strange signs of screen corruption and flickering.
I thought i could circumvent the bug by using rekonq and flash 10.2 but 
the same problem exists there and when hovering over a youtube video, the browser crashed.

The crash can be reproduced some of the time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault

Sorry, I cannot reproduce your crash. I need at least one testing site where this (at least sometimes) happens

Comment 2 Andrew Crouthamel 2018-09-19 14:43:08 UTC

This bug has had its resolution changed, but accidentally has been left in NEEDSINFO status. I am thus closing this bug and setting the status as RESOLVED to reflect the resolution change.
