Geoprocessing Difference is too limited?

I have a problem with QGIS 2.6's Difference Geoprocessing feature. In my project, I have to cut hundreds or thousands of small vector polygons from a bigger polygon area, the small being trees and the big one a region. For some reason if the bigger polygon area is too massive the process seems to fail and create a dump file, which is the one as follows (about 27,7MB):
Is there any limit for this tool that makes it not even try to process the data?

I've fixed the problem by using the Dissolve tool in the tree layer. If I use a dissolved layer, it processes properly. Which makes no sense to me, since it is still a massive ammount of minuscule polygons that are distant from each other, but it works, so all good.
Thanks for answering.
