Can't understand from where the error comes. so i just copy+paste what it says :

MemoryError

Buy RAM :)

More seriously, the problem occurs because you're running out of memory while rendering what is probably a huge changeset.

0.10 has some ways to manage resource consumption in this case, see the [changeset] max_diff_bytes configuration option.
