How sound is the Hadith: "If my nation practices fifteen traits, tribulation will befall it"?

The aforementioned hadith was narrated by Al-Tirmidhi and was deemed weak by Al-Albani in "Da'if Sunan al-Tirmidhi," "Al-Silsilah al-Da'ifah," and "Da'if al-Jami'." He also described it as "very weak" in "Da'if al-Targhib wa al-Tarhib," and he likewise deemed it weak in "Al-Mishkat."
