Cannot create/edit issue on custom domain

When I click to create (edit) issue button (form is generated OK) it generates 404 error. I have found where the problem is:

On bitbucket, there are repositories behind url in this format: http://bitbucket.org/[user]/[repo]/*

On custom domain, they are behind url: http://[domain]/[repo]/*

But the Create/edit button calls action on the url in format: http://[domain]/*[user]*/[repo]/issues/new.. And that's the problem.

Sorry for some english mistakes, but I'm not native english...
