TYPO3 Core

Testcase: Create a content element with a single empty <p> </p> in the RTE.

Result: Two paragraphs are renderd in the Frontend (<p class="bodytext"> </p><p class="bodytext"> </p>)

Expected result: Only one paragraph should be rendered. (<p class="bodytext"> </p>)

Cause: In the encapsLines functionality the string is splitted by \n. When you have only one \n without any content before or after it, explode() will get you two empty items that are treated as lines.
