I experience the same problem. I did some analysis with valgrind and noticed that the problem isn't dia itself, but the text-layout library 'libpango'. On every redraw event some pieces of font information are gathered by that library, but won't be cleaned up again so that dia (and any other program that uses certain functions of libpango) takes more and more memory until it has to be killed because there is no more space left ( so called "memory leak"). This explains the OOMs the original poster experienced and why it only happens when text objects are involved.
