Version:           Version 1.1 Using KDE 4.1.00 (KDE 4.0.99 (4.1 RC1+)) (KDEmod) in ArchLinux (using KDE 4.0.98)
Installed from:    Compiled From Sources

Dolphin/Konqueror Using KDE 4.1.00 (KDE 4.0.99 (4.1 RC1+)) (KDEmod) in ArchLinux
QT 4.4.0 + qtcopypatches
Firefox 3.0.1
JRE 6u7

When trying to drag and drop some file from Dolphin/Konqueror to Firefox (at www.fileai.com) java applet, the application crashes

Step to reproduce:
- Open Firefox and go to www.fileai.com
- Select "Send File" , a java applet will appear.
- Open a Dolphin window and try to drop some file into Firefox. When the mouse is 1px inside Firefox, Dolphin crashes.

Konqueror (file browser) will crash too.

If you have another tab on top (other side) , Dolphin will still crash when trying to drop some file.
After closing the www.fileai.com tab, the behaviour is the same.

If you never opened www.fileai.com java applet, this will not happen.

It doesn't happen in Opera (but I can't drop files either)
I can't test in Konqueror Web Browser (it says Java is disabled/non-installed)

--------------------------

I reported this bug to QT bugtracker, but their response was:

Hi Darío

It may indeed be a bug in Qt, but it may also not be. We can't do much
with the backtrace and we're not going to test Dolphin ourselves.

However, if the Dolphin team can write a small Qt-only program that
reproduces the problem (running against an unpatched Qt), we will be
very interested in analyzing the issue, of course.
