But, it fails if I return a tuple containing the size and the string (a 
message indicating a wrong return type is shown). It only work if a tuple 
containing a single string is returned. If I understand sip (I first looked 
to the *.sip yesterday) I would say it is due to this line in 
%VirtualCatcherCode of readBlock in qiodevice.sip :

sipParseResult(&sipIsErr,sipMethod,result,"(O)",&buf);

My Qt version is > 3.0.0 but the same line is used twice so I think it is the 
same for all versions.
