           Summary: 64bit specific bug in KDEPrintd::processRequest()
           Product: kdeprint
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kde-print-devel kde org
        ReportedBy: geromanas mailas com


Version:            (using KDE KDE 3.5.5)
Installed from:    Debian testing/unstable Packages
Compiler:          gcc 4.1.1 
OS:                Linux

Attempting with to Print Server->Configure Server usually fails with the following error message:

Unable to configure print server. Error message received from manager:
Unable to retrieve configuration file from the CUPS server. You probably don't have the access permissions to perform this operation.

Then ~/.xsession-errors gets a warning:

---
Cannot communicate with kded_kpasswdserver
----

As it later turned out, actual KIO::AuthInfo queryAuthInfo(KIO::AuthInfo,QString,long int,long int) never gets called because KPasswdServer::process(const QCString &fun, const QByteArray &data, QCString& replyType, QByteArray &replyData) fails due to insufficient arguments at:

arg >> arg2;
if (arg.atEnd()) return false; // arg.atEnd() returns true though there is still an argument (arg3) pending

The reason for this is due to incorrect notation of long int constant and assumtion that sizeof(int) == sizeof(long int) which is wrong on 64bit architectures. The attached patch fixes the problem.
