nautilus hangs when opening a folder which containing version controlled sub-dir (nautilus-bzr)

[BlueT - Matthew Lien - 練喆明]

Everytime I browser my work folder in my home dir, nautilus hangs.
This work folder contains some version controled sub-folder, and some svn upstream is no longer availiable or not able to connect to without VPN.

This is what I saw:

Let me translate some chinese words into english:
"傳回 255 錯誤訊號" in "Nautilus-Share-Message: Called "net usershare info" but it failed: 'net usershare' 傳回 255 錯誤訊號"
means "255 Error Code Returned".
"沒有此一檔案或目錄" in "net usershare: cannot open usershare directory /var/lib/samba/usershares. Error 沒有此一檔案或目錄"
means "No such file or Dir"
"無法連接到伺服器" in "bzrlib.plugins.svn.errors.DavRequestFailed: A Subversion remote access command failed: OPTIONS of 'http://172.28.28.28/svn/parser': 無法連接到伺服器 (http://172.28.28.28)"
means "Cannot connect to server"
