Dub hanging for a long time

[Suliman via Digitalmars-d-learn]

Several times I encounter problem when DUB is hanging for a long 
time
It's look like that when I tun DUB from folder of current project 
it's do not show me nothing, just move cursor on next line for a 
long time.

running dub from any other location is fine.
If to wait some times (about 1 minutes) it's begin build project. 
After it next running dub from project dir work mediately.

Does anybody encounter such problem?
