We should always match the number of >> that were done in the stream, otherwise everything will go wrong.
If a.d is null, then we can't restore the item. We should warn, then, and probably restore the 3 fields into temporary (thrown away) variables.
If on the other end a null item was streamed in (empty URL), then we should 1) check for that (you missed that step: if url.isEmpty() { nothing else to stream out } ), and 2) well, make "a" null, so delete a.d; a.d = 0;</pre>

Patch based on similar code from QImage.
I'd like to draw your attention to these issues:
1) KFileItem::setUDSEntry()
For a null KFileItem, this should probably create a new d and initialize it. Ideally, we'd have a dedicated public function to do that (see QImage::create()), but since we can not change the public API (or can we?), I put the new in setUDSEntry(). Anyway, this is now the only interface function that can init a null KFileItem (before the patch, there had been none). All the other set* functions do not new the d, but rather return on d == 0.
2) KFileItem::cmp()
What should this return for a null KFileItem? I return false, but still, it feels wrong to me.
3) operator << / operator >>
<< returns "null KFileItem" for d == 0 and >> does nothing, returning the original stream unmodified. operator << thus duplicates the public operator <<(QDebug&).
4) This also overrides dfaure's patch for KFileItem::metaInfo(). There is a
return d->metaInfo()
at the end of the function, so this can crash as well.
All the classes' objects that are default-constructed and then returned in the case of d == 0 can be checked for validity, looked it up in the code.</pre>
