Most flicker problems are caused by GI, in my experience.

You should turn it totally off. That, or increase the quality to a higher value - 3 or 4 maybe? Higher qualities will have less variation in the lighting - you'll get more consistent results.

Also you might want to increase the overall render quality to something higher than 0.3. This will probably also reduce the flicker.

It's definitely the GI. There are various solutions. As Blonderator said you can increase GI detail - this will greatly increase render time though. Also keep in mind that part of the GI detail is relative to overall detail, so using a higher base detail like 0.5 or even 0.7 would help too. Another option would be to use fill lights instead of GI. Unfortunately this would greatly change the look of your scene, but most of its character could be emulated with adjustments to the settings under a fill light setup.

There are additional GI settings coming in the next release which should help in situations like this.
