Multiple choice questions – are they always leading?

I'm designing a survey in which I want to know what kind of problems with my software my users have.

I wonder if I should create one big open-text question? Or should I suggest some answers and go with multiple options question (with an open-text answer at the end?).

Personally, I prefer the multiple options version. I think that by giving examples, it'll help my users to come up with their own ideas.

What's your opinion?
