Maybe this is related? Applying the Processing buffer on a memory layer returns an error:
2015-06-08T08:25:25 2 Uncaught error while executing algorithm Traceback (most recent call last): File "/home/paolo/python/plugins/processing/core/GeoAlgorithm.py", line 225, in execute self.processAlgorithm(progress) File "/home/paolo/python/plugins/processing/algs/qgis/FixedDistanceBuffer.py", line 72, in processAlgorithm dissolve, segments) File "/home/paolo/plugins/processing/algs/qgis/Buffer.py", line 45, in buffering total = 100.0 / float(len(features)) ZeroDivisionError: float division by zero

Paolo's error is casused by trying to running the buffer with an empty layer. I will fix that separately, to handle that case more gracefully instead of breaking and showing an error trace

Thanks for your work, I will test it in my master version asap.
