Bye,

Fireboot.

Comment 1 Dario Andres 2008-08-01 22:01:14 UTC

Using KDE 4.1.1 (KDE 4.1.0 (4.1 >= 20080722)) (KDEmod) in ArchLinux i686:
I can't reproduce this bug. I could even upload an image. 
May be a regression in trunk

Comment 2 fireboot 2008-08-01 23:57:14 UTC

A friend who use KDE 4.1.0 can't reproduce this bug too, so it appears like a regression in trunk, or maybe a problem from my installation ?

Comment 3 fireboot 2008-08-02 00:13:01 UTC

I got the same bug on hiboox.com, another website to store pictures, when clicking on the file browser icon.

Here is the new backtrace, hope that it will be useful

Comment 4 Dario Andres 2008-08-02 02:01:37 UTC

The bug 168047 is a duplicate of this (same backtrace and description) . Seems to be a problem with the File Chooser Dialog (KFileWidget)

Comment 5 Frank Reininghaus 2008-08-02 02:11:38 UTC

Simple testcase.

Crash confirmed on SVN trunk rev. 840693 (just click icon next to the input
field). Does not crash in 4.1.

Comment 8 fireboot 2008-08-02 02:19:50 UTC

I confirm that the Frank's testcase crashs konqueror too.

Comment 9 Frank Reininghaus 2008-08-02 02:23:25 UTC

I'm not sure though if Konqueror is the right 'product'. Maybe the bug should be reassigned to some kdelibs component?

Comment 11 Frank Reininghaus 2008-08-04 01:15:29 UTC

It looks like this regression was caused by the following commit:
http://websvn.kde.org/?view=rev&revision=838026

I verified that kdelibs rev. 838025 opens the file dialog fine and rev. 838026 crashes. I'm CC'ing the developer who committed it.

Comment 12 Rafael Fernández López 2008-08-04 02:10:25 UTC

Frank, I disagree that the commit you pointed out has to do with this issue. I'd say the commit (also from me) was http://websvn.kde.org/trunk/KDE/kdelibs/kfile/kfilewidget.cpp?r1=817311&r2=817356.

I need to have a deeper look at this. Thanks.

Not crashing

Actually, this patch is not a fix, but is a demonstration of why probably the
bug wasn't introduced by my commits. If you apply it, you will see your
rendering is not being properly updated, but the crashing stops, so it seems
something related to redirected/non redirected widget painting. Also, all
applications that triggers this open/save dialog are not crashing, so that's
another point for this bug remaining in Konqueror side, not in kdelibs side.

Assertion failure

Also, if you apply this patch you will see KHTML is trying to render in a
painting device which isn't active. From my understanding this can lead to lots
of problems, and one of them are unexpected results as we are getting.

I am almost sure now this is a KHTML issue. You will see how you are getting an
assertion failure every time KHTML will try to render any form.

Comment 15 Rafael Fernández López 2008-08-04 03:04:16 UTC

Adding Germain to CC, since he is the maintainer of widgets-on-khtml. Suggestions Germain ?

Comment 16 Rafael Fernández López 2008-08-04 03:14:26 UTC

Actually, after reading again QWidget::render I realized the painter device needs to be ended() before calling to render, so that part is fine. Forget the assertion failure, that is fine.
