qTranslate has a serious bug, which causes:
1. It to insert a new line every time I click refresh at the start and at the end of an article. Whenever it happens when loading or when saving (it seems at loading), I don't know I just know that an article starts a line lower then it supposed to!
2. When used without TinyMCE Advanced's line brake fix, it does not look like a problem, as the wordpress formatter cleans all the code every time, so it stripes empty lines.
3. But when used with TinyMCE Advanced's line brake fix, the new lines get converted into <br class="spacer" /> to save them, so the page gets <br class="spacer" /> <br class="spacer" /> <br class="spacer" /> as many times as you have saved the article.
I have written detailed examples below, where first I thought that this behaviour is because of TinyMCE Advanced, but its not, it's a bug on qTranslate's part!
