Bug#585526: libwebkit-1.0-2: Webkit-gtk generates TCP/UDP flood while surfing the WWW

Fri Jun 11 12:01:56 UTC 2010

Package: libwebkit-1.0-2
Version: 1.2.1-2
Severity: normal
Tags: squeeze

Hello, i decided to leave iceweasel (or any gecko-based browser) and start
using webkit-based browsers. I started with midori but then switched to
epiphany. Using those browsers i saw that when i open links, sometimes i get an
error: cannot connect to the host or cannot resolve host. Once i got that
error, i can't connect to any website for few seconds. After 15-20 seconds, i
can surf the WWW again.

I thought it could be a DNS trouble, but used other and the problem was not
solved. Once, while waiting 15-20 seconds, i decided to try to connect my
router and connected with no problem, so it is not a network problem. Loaded up
the log from the router and this is what i see every time the browsers can't
connect to host:

To confirm that is not a network problem, i booted up my netbook and loaded the
same browser i used in the main computer: while in main computers the error
appears, i could surf the WWW from my netbook. Then i did the reverse
situation, inducing the error in my netbook while i could suft the web from the
main computer. So the problem must be the software.

I installed iceweasel 3.5.9, galeon 2.0.7-2.1+b1 and chromium 48420 (plus
epiphany-webkit 2.30.2, midori-0.24 (then midori-0.2.6)). There was no problem
using iceweasel, nor galeon, nor chromium. The log from router was as usual.
The coincidences: epiphany and midori uses the same webkit release
(libwebkit-1.0-2 v1.2.1-2), which is different of the used by chromium.

So i think there is a problem with libwebkit-1.0-2.

P.S.- This is my first bug report, so excuse me if there is not the information
you need. If so, ask for more info.
