Bug 196359

Version:           0.1 (using KDE 4.2.2)
OS:                Linux
Installed from:    Unspecified Linux

Problem description:
-----------------------------------------------------------------------------
After some time rekonq fails to load pages. (the string "Laden fehlgeschlagen"
is displayed in the status bar in the lower left of the window. Obviously, I'm
using the german localisation). After trying to refresh page, the displayed
page seems to be either empty or pictures/elements are missing from the site
(see attached screenshot for an example) 

How to reproduce :
-----------------------------------------------------------------------------
Surf some time. Having many tabs open and/or surfing sites with many embedded
images or player plugins (e.g. last.fm, youtube.com, etc.) seems to cause
the problem to occur earlier, but this is more or less a gut feeling.

Expected Behaviour :
-----------------------------------------------------------------------------
Obviously, load pages correctly regardless of browser history


System Info : 
-----------------------------------------------------------------------------
I'm using version 0.1 compiled from the official tarball together with 
KDE 4.2.2 and Qt 4.5.1 on a P4/2GHz. The rekonq package was created using
an AUR build script for Arch Linux, KDE 4 and Qt were installed from the
vanilla binary packages.

If necessary, I can provide the build script and/or rebuild the package
and forward the log messages during compilation.

Further information:
-----------------------------------------------------------------------------
If I start rekonq from konsole, the following  messages appear
when the error is triggered:

The stanza following the QNetworkReplyImpl message corresponds to the output
of one (failed) attempt to reload the page in question.
