New directories in ~ after installing IDEA 12.0.4

I recently installed 12. on my system, switching from an earlier EAP version.

And now I notice two new directories in my ~.

1. ~/Snapshots/
2. ~/var/log/

Does IDEA or PyCharm create these directories?

The creation of ~/Snapshots comes about 2 minutes after installing IDEA. ~/var doesn't seem to correlate with the time... but I don't remember it being there before. ~/var/log/ is empty.
