Comment 1 Gérard Talbot (no longer involved) 2011-08-31 01:00:17 UTC 
Dimitrios,

I went to
http://www.papaki.gr/
and the popup "applet" (it's possibly - just a hunch - a DHTML-driven form that expands and collapses) to input the username and password is replaced with the following between curly braces "{" "}"

{
Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>


Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>

and I did *_not_* crash. So, I can *_not_* confirm your issue with such site.

I am using
KDE Platform Version: 4.7.0
Konqueror version: 4.7.0 (KHTML rendering engine)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic-pae i686 (32bits)
Distribution: Kubuntu 11.04
here.

I also get that same webserver error message when using Firefox 6.0 and when trying with Opera 11.50. There is very high chances here that the problem is with the people behind the papaki.gr website.

If you crash again, then please provide a backtrace log again and information about the rendering engine you are using (KHTML or webkit). We will also have to reedit the bug summary a bit (to include papaki.gr) to help search for duplicates, QA, etc.

If you no longer crash, then please RESOLVE this bug report as WORKSFORME.

regards, Gérard
