Can't confirm. Backtrace?

Only one which is deemed useless. I have all dbg packages from Debian installed, yet that seems not to be enough.

Any interest a dump that does not have many symbols in it? If yes, I can append it.

Won't hurt --- might at least give library names or something.

Funny, with KHTML, it does not happen.

I am really starting to hate Webkit. Three regressions over KHTML in two days...

At any rate, please don't file bug reports involving QtWebKit under Konqueror --- use kdelibs/kdewebkit for those. 

@WebKit people: you really should do something to not run Flash in the same process.

I didn't do it on purpose ;)

But yes, I will always check with KHTML before I file bugs, from now on.

(In reply to comment #5)
> Funny, with KHTML, it does not happen.

Why is that surprising ? QtWebKit and KHTML are about the same as KDE 4.0 and KDE 2.0.

And the other two are ? Just like blogs, and forums are not the right place to report bugs, this is not the place for sarcasm and opinions. Thanks.

Or better yet report it upstream since kdewebkit is nothing more than a thin wrapper to KDEify QtWebKit and provide convenient functionality. This bug affects all webkit based things ; so this needs to be reported at http://bugs.webkit.org not here...

> @WebKit people: you really should do something to not run Flash in the same

They are already working on it... I also personally tried to use nspluginviewer for flash in kdewebkit but unfortunately doing so has its own many issues. *sigh*

True, I should not have added that. The other issues live on upstream's bug tracker.

Hmm, it's too late for my own good, I read over comment #9 , just now.

I will report the issue upstream after some sleepy-eye.

Great. When you open the bug report upstream, can you please post url to that ticket here ? We can then close this ticket as UPSTREAM with the proper reference to the upstream report. Thanks...

Eould have done so, anyway. Thanks for keeping the bug open and not just marking it RESOLVED UPSTREAM immediately. I appreciate it :)
