QUrl behavior and KIO

[Marco Martin]

Hi all,
porting a couple of kio slaves (trying to make sense of the trash kio partly 
ported to kf5 in a gsoc) i noticed what appears to be a slight behavior change 
compared to when it used KUrl

something like this in kde4 was working:
KUrl u;
u.setPath( "/some/valid/path" );
KIO::Job* job = KIO::move( u, KUrl("trash:/"), KIO::HideProgressInfo );

something like this doesn't:
QUrl u;
u.setPath( "/some/valid/path" );
KIO::Job* job = KIO::move( u, QUrl("trash:/"), KIO::HideProgressInfo );

TrashProtocol::rename() doesn't even get called (there is on stderr a message 
unknown protocol '').

while instead something like this work:
QUrl u = QUrl::fromLocalFile( "/some/valid/path" );
KIO::Job* job = KIO::move( u, QUrl("trash:/"), KIO::HideProgressInfo );

because u is now file:///some/valid/path

what should be done? modify kio to make qurls without scheme work (and assume 
they are file://) or modify all the users to make sure a scheme is always 
passed?

Cheers,
Marco Martin
