Public bug reported:

Architecture (64 bits or 32 bits) : 64
Operating System & version: Kubuntu 13.04
Installation Method : Ubuntu repository
Version of Openshot installed : 1.4.3-1
BZR Revision used (if any) : 
MLT/melt version:  0.8.8-1
FFmpeg (i.e.libavcodec) version : 6:0.8.6ubuntu2
FFmpeg installation : 6:0.8.6-1ubuntu2

I'm editing two 720p MP4 clips totalling around 10 minutes of video.
One clip has been cut several times and has some sped up, with a
transition between two of them.  There is an MP3 track in the background
as well.  After several minutes of editing, my computer starts rapidly
paging to disk, with 14GiB of RAM usage by Openshot.

I have attached details about various package versions.
