Hello All,

According to the wiki on adding expert
info(http://wiki.wireshark.org/Development/ExpertInfo):
"Remember: The tree variable might be NULL, so the call to
expert_add_info_format() should not be inside any "if (tree)" block!"

However, their are many protocol dissectors (including some with
expert info) which only dissect in a if(tree) block.

What is to be done in such cases... do we go ahead and add expert info
anyway? Or do many dissectors need to be re-written to better support
this and other functionality while still trying to optimize?

Thanks,
Abhik.
