Glanceclient is trying to create ~/.glanceclient, and crashes if it can't do that. In some environment (for example, when building the package under Jenkins), writing on $HOME is simply not allowed, and Glanceclient can simply ignore it. This patch allows the mkdir() to fail, which fixes the issue. Closes-Bug: #1446096 Change-Id: Ib3591fb4e54ccd2fe63a1a4815551ac10ef5b961
