How can I use a logarithmic ScalingFunctions with ListContourPlot and DataRange? (i.e. no x- and y- inputs given)

Question

There appears to be a bug in plotting, using ListContourPlot with ScalingFunctions->{"Log","Log"} and specifying a DataRange, when trying to plot only a 2d array (i.e. with the x- and y- variables specified using DataRange instead of being input).
Providing a 2d DataRange gives a blank plot, with PlotRange having no effect.  If I include "All" as a 3rd dimension to DataRange, then the plot draws axes as Exp[DataRange].
Could somebody help me around this apparent bug?

It looks like ScalingFunctions does not work with numbers below the base of the logarithm. Conider e.g.:
n = 20;
dat = Table[x^2 + y^2, {x, 1, n}, {y, 1, 2 n}];
ListContourPlot[dat, DataRange -> {{1, n}, {1, 2 n}}, 
 ScalingFunctions -> {"Log", "Log2"}]

Or the same with Log10:
n = 20;
dat = Table[x^2 + y^2, {x, 1, n}, {y, 1, 2 n}];
ListContourPlot[dat, DataRange -> {{1, n}, {1, 2 n}}, 
 ScalingFunctions -> {"Log", "Log10"}]

I think this is a bug. Please report it to "support.wolfram.com"
