Hmmmm....I would read that as a caution against believing in what men say about God and not relying upon our own interpretation. It is an excellent verse for sola scriptura.
Hardly. Don't you know that the teachings of the Apostles are from God??? I would beware of your own private interpretations, considering you would be one of those "cursed men who trust in man" (yourself). Catholics trust in what God has revealed through the Apostles, the teachings from God.
"As we said before, so say I now again, If any [man] preach any other gospel unto you than that ye have received, let him be accursed. For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ. But I certify you, brethren, that the gospel which was preached of me is not after man. For I neither received it of man, neither was I taught [it], but by the revelation of Jesus Christ. Gal 1:9-12
Take heed, brother. Accept the teachings of the Apostolic Church, not your own teachings.

It is an excellent example of sola scripturologists reading whatever pleases them in whatever you quote to them.
This is what is in the reading:
5 Thus saith the Lord: Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the Lord.Some hearts depart form the Lord. Hardened or not.
7 Blessed be the man that trusteth in the Lord, and the Lord shall be his confidence.And some hearts do not depart. Note that in either case, both departing and not departing are described as acts of men; the cursing or the blessing is in response to these movement of heart.
9 The heart is perverse above all things, and unsearchable, who can know it? 10 I am the Lord who search the heart and prove the reins [...]God knows the heart and God gives laws, but the heart acts in its own perverse way despite all that.
10 I am the Lord [...] who give to every one according to his way, and according to the fruit of his devices.That fickle heart leads to act, and God judges the fruit of the act. Free will, in other words.
