kdenlive renders wrong section of clip?

Hey there. Well, I'm currently running the Ubuntu build from Trevino's reps, and everything is running swimmingly, EXCEPT for one glaring exception:

I add a clip, mark in and out points in the clip viewer, and then drag from the window to the timeline. Everything is cool, until I render. Rendering goes fine, but when I playback in a media player, it's the wrong section! Right amount of time, but it seems to either jump it ahead of where I selected, or before.

Has anyone else had this particular problem?
