Unfortunately, PyPRP is known to be a memory hog. That backtrace doesn't point at a particularly memory-hungry place, so your memory must have been filled up somewhere before that, and such problems are notoriously hard to debug.
Have you tried the suggestions made in otherthreads about memory errors?

A few of them. I've tried saving/closing blender/open blender/export but no luck. I've tried re-starting the PC itself, nothing, I've tried deleting the said mesh that caused the error, it just moves to another. The only other thing I have not tried is to replace a file with an updated one posted in the other memory error forums, i cant due to the fact that the links are dead.

The 1.5.0 release is pretty outdated by now. And it does not have Christian's memory fixes.
People should really install the bleeding edge version at this time. Under our new release management this version is not likely to break ages unexpectedly as it used to do in the past.
I have attached the trunk files from the latest revision (416) before the svn server went down.
