KIO error system question

[Hamish Rodda]

I'm in the process of working in a way for kioslaves to report errors in 
detail to fit in with the error documentation work I did a while back. What 
I'm trying to accomplish is the following:

When a slave emits error(), it sends a QString errorText. I want to be able to 
send more structured data (a few QStrings and QStringLists) through 
errorText, and tried creating a QByteArray and QDataStream in order to stream 
these objects into the errorText QString.

The problem is that the resulting QByteArray has lots of zero-value chars in 
it, so when the QString is created to send back, it is of length zero.

Can anyone think of a fix for this (or a better way to do it)?

Thanks,

Hamish.

Data I'm trying to pass:
QString errorName - the name of the error
QString techName - if not null, the technical name of the error
QString description - a description of the error
QStringList causes - a list of possible causes of the error
QStringList solutions - a list of possible solutions for the error

Example code:

On the IOSlave side:
        QByteArray data;
        QDataStream stream( data, IO_WriteOnly );
        stream << customErrorName << customTechName << customDescription
          << customCauses << customSolutions;

	// Here the errorString is empty as data starts with a few zero-value chars
        errorString = QString::fromUtf8( data );
        error(ERR_CUSTOM, errorString);

On the receiving side:
        QByteArray input = errorText.utf8();
        QDataStream stream(input, IO_ReadOnly);
        stream >> errorName;
        stream >> techName;
        stream >> description;
        stream >> causes;
        stream >> solutions;
