Description
When I clip raster (cell size 5x5m) to polygon (both in GDA94 Z56 - EPSG:28356) the result has very slightly unequal cell size like:
Pixel Size = (4.999893471194129,-5.000074452387987)
It might seem like nothing but some tools needs exact square dimensions which makes in these cases clipped grids useless...

are you using the "clipper" tool in the raster menu?
if yes then the tool is just an interface of gdalwarp command line utility. You should test run the same clip operation directly from the command line (qgis shows you the command), if the result is the same then is a gdal issue not a qgis one.

Yes, I think it is gdal_warp issue. I reported it on http://trac.osgeo.org/gdal/ticket/5733. Thank you.
