[TYPO3-core] RFC: #10954: Validation issue: Images with empty attributes in Module menu in BE

[Patrick Broens]

Hi,

this is a SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=10954

Branches: Trunk

Problem:
The main modules in the module menu don't have any image assigned. This
leads to the output of complete empty images like <img src="" title=""
alt="" /> which generates markup warnings.

Solution:
Don't render the image tag in typo3/classes/class.modulemenu.php when no
image is available.

Cheers,

Patrick
