Bug report #13067
The difference tool gives broken results in both 2.10 and 2.11
|Affected QGIS version:||2.10.0||Regression?:||No|

|Crashes QGIS or corrupts data:||No||Copied to github as #:||21137|
Running the difference tool (vector menu and processing) in QGIS 2.10 and master gives broken results.
Instead of removing features, the layer contains invalid geometries.
No error is raised, but the layer can't be used for a further analysis.

- Target version changed from Version 2.12 to Future Release - High Priority
- Priority changed from High to Severe/Regression
This is the second (basic) vector geoprocessing tool we at the moment see also #11986 (not to speak about how slow they all are).
I really think that this tools should be really fixed once for all as any gis user expect them to work and having to say "don't use the intersection/difference/whatever tool is kind of embarrassing. It even could be dangerous... what about if I take for good the result of one of this operations and then give wrong results that have a real world (legal for example) impact?
Now that we have the routine to create virtual vectors I plan at some point to add the same basic tools based only ogr/sql/geos (there are already a few in Processing).
