stitchMesh -perfect - tolerance error of 2 identical faces

after reading all stitchMesh regarding threads, i decided to start a new one. I meshed 2 parts of a rectangular channel with blockMesh and now im trying to merge the meshes. mergeMesh works with no problem, and after it, i got 2 regions in the mesh and some non-aligned edges.
So i go to stitchMesh next, but it aways complains about:
--> FOAM FATAL ERROR: Points on patch sides do not match to within tolerance 1.1156e-06 From function perfectInterface::setRefinement(polyTopoChange& ref) const in file perfectInterface/perfectInterface.C at line 220. FOAM exiting

for every point.
I have checked the 2 faces that shoud be stiched with paraView, they are absolutely identical, the geometry is most simple. The tolerance between the points should be zero, instead its pretty high, as you can see.
I have absolutely no idea whats going wrong here, since the test-case with a very coarser mesh worked perfectly.
Thanks for reading
