Using version 3.2.6 in Windows, starting this morning my push dialog is empty. I can fetch, commit, or merge just fine. And after merging or committing the button shows how many things need to be pushed. But the push dialog is empty, as in it doesn't show any branches. Before today it always showed all the branches, with the one I had checked out selected by default. Now there are no branches in the list at all. This is true no matter which local repository I am working in.
I should also note that if I use the command line, the push works just fine.
Any hints about how to fix this are greatly appreciated.
