Comment 1 for bug 412058

Gary, I need your opinion on this bug.

Recent changes fromn Javier discover that our throbber practice is not sufficient here. At all.

Now directory picker become visible right now but it's not available anyway until find_branches finished, because all this time window just not respond on user actions. So we should find another way to unblock UI.

Possible solution I see:

1) Put find_branches action into separate thread. I remember Lukas was always against threads in the QBzr.

2) Put find_branches action into subprocess, similar to what bzrtools' "branches" command do: emit found branch names to stdout and run subprocess output in the throbbered action.

3) Just disable find_branches and forgot about it?
