Steps to reproduce: 1. mount a filesystem in favorites view 2. clone a hg repository into a folder of the filesystem 3. delete the cloned folder (repository folder) The folder disappears for a while but than appears again and only its .hg folder is missing. The folder cannot be deleted by IDE.

Can you send me the repository you cloned? I am have difficulty reproducing this.
I used several local test repositories created by: mkdir test cd test hg init cp somedata . hg commit I think it does not depend on the repository structure.
I can reproduce this.
