Following those instructions exactly I get an error message of "The specified diff file is empty", which is not surprising since file2.txt was never added to the repository.

If I do "hg add file2.txt" before the first qnew on the other hand, "hg postreview" works fine and correctly shows Line2 being added to file2.txt.

If it is still breaking for you even with the hg add, can you let me know what versions of mercurial, ReviewBoard and the reviewboard extension you're using?

If you're using the latest versions and it still doesn't work, please send me the output of

hg postreview --debug --apitrace

I've managed to recreate the problem such that 'rbt post' works and 'hg postreview' fails: first, on the remote server create a new repository with "hg init". Then, in Windows (with Python 2.7), run:

hg clone <repo> rbtest01
cd rbtest01
echo Line1 > file1.txt
hg add file1.txt
hg commit -m "initial commit"
hg push
echo Line1 > file2.txt
hg qnew first
echo Line2 >> file2.txt
hg qnew second
hg postreview

If you don't create file1.txt and try and create a review with an empty repo then 'rbt post' fails too, with:
