Comment 1 Maksim Orlovich 2010-05-22 14:04:41 UTC

Can't confirm. Backtrace?

Comment 2 Richard Hartmann 2010-05-22 16:23:07 UTC

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.

Comment 3 Maksim Orlovich 2010-05-22 18:41:24 UTC

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

Comment 5 Richard Hartmann 2010-05-22 20:38:04 UTC

Funny, with KHTML, it does not happen.

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

Comment 6 Maksim Orlovich 2010-05-22 20:56:36 UTC

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.

Comment 7 Richard Hartmann 2010-05-22 21:05:53 UTC

I didn't do it on purpose ;)

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

Comment 8 Dawit Alemayehu 2010-05-23 00:22:30 UTC

(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. 

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

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.

Comment 9 Dawit Alemayehu 2010-05-23 00:29:48 UTC

(In reply to comment #6)

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
> process.

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*

Comment 10 Richard Hartmann 2010-05-23 02:29:10 UTC

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

Comment 11 Richard Hartmann 2010-05-23 02:30:51 UTC

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...

Comment 13 Richard Hartmann 2010-05-23 21:04:51 UTC

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