Glade Plug-Ins Flammable?

I was recently told a house burnt down and plug-ins were determined to be the cause. Is this possible? Just wondering.

From Snopes:

Snopes also provides this link to the Glade FAQ which states in part:We suspect this rumor may be associated with a past SC Johnson voluntary recall of one of its air freshener products, a Glade® Extra Outlet Scented Oil product that was sold for a short period before June 1, 2002. After discovering an assembly error in a small number of that product, SC Johnson implemented a voluntary recall and provided extensive information about the product to the U.S. Consumer Product Safety Commission (CPSC). After revising the manufacturing process and thorough testing for proper assembly, the Glade® PlugIns® Scented Oil Extra Outlet product returned to store shelves on June 3, 2002. SC Johnson has no knowledge of any credible reports of fire related to this product.

We also know that our products do not cause fires because all of our PlugIns® products have been thoroughly tested by Underwriters Laboratories and other independent laboratories and our products meet or exceed safety requirements.SC Johnson continues to work closely with the Consumer Product Safety Commission to investigate allegations involving PlugIns® products.
