Review request for KDE Edu, Albert Astals Cid, Frederik Gladhorn, Peter Hedlund, and Jeremy Paul Whiting.


Description
-------

When e.g. KWordQuiz writes a document with images, the XML writer tries to use relative paths. This fails, because the URL of the document to be saved is set _after_ writing the document.

Attached patch fixes this issue by changing m_Url before calling the writer. In case of an error, it is set back to the old (previous) value.

Somewhat related is the change in the writer. Initially I had the impression the "is URL A relative of URL B" check using "startsWith" string compares was the culprit. Since KUrl offers an own function, I kept this change.


This addresses bug 318787.

Testing
-------

Tested with KWordQuiz using the steps from bug 318787. Images that are not outside the document directory are stored relative.


Thanks,
