Sorry for the non working suggestion, then. But I'm still confused about this code, it doesn't make sense to me.

The current code says:
 (1) Has directory -> use full url as start dir
 (2) No scheme, or local file -> set as fileName, use default dir
 (3) Otherwise (other protocols, but with no directory) -> use full url as start dir

So, currently:
  "ftp://foo/bar/", "file:///tmp" -> full url (rule 1), OK
  "foo.jpg" -> fileName (rule 2), OK [this is the "save image as" case]
  "smb://", "smb:" -> full url (rule 3), OK  [this is the bugfix that led to this review request initially]
  "foo/bar" -> has directory, so this is used as start dir URL, i.e. the method returns a relative URL. Surprising, I wonder if it works.

The "or local file" part of rule 2 seems pointless, a file URL always has a directory ("file:" doesn't exist, and KUrl("fileName").isLocalFile() is *false* nowadays). So a file URL will always use rule 1 anyway.

My suggested patch was "if relative, set as fileName". Needs adjustment for the corner case "foo/bar", but other than that, it should work.

Proof:
  QVERIFY(KUrl("smb://").directory().isEmpty());
  QVERIFY(KUrl("blah").directory().isEmpty());
  QVERIFY(!KUrl("foo/bar").directory().isEmpty());
  QVERIFY(!KUrl("blah").isLocalFile());

Ah, the konqueror breakage comes from this code (kwebpage.cpp and khtml_ext.cpp) :

118│     const QString fileName = suggestedName.isEmpty() ? srcUrl.fileName() : suggestedName;
119│     // convert filename to URL using fromPath to avoid trouble with ':' in filenames (#184202)
120├>    KUrl destUrl = KFileDialog::getSaveFileName(KUrl::fromPath(fileName), QString(), parent);

This turns "foo.jpg" into "file:foo.jpg", i.e. "file://foo.jpg". Ouch.
More from me later...

So the solution I thought is to check if the schema is not empty, in case both directory and schema are empty the KUrl will be discarded as well, instead if any of them is not empty the directory will be used.
