Guarding against the NPE and printing some values in ConfigureAppearanceAction around line 141 shows:

The profile ids are [apache.snapshots, cargo-config, repo-config, local-settings, archiva-localhost]
profile is org.apache.maven.settings.Profile@d53eeb
profile is org.apache.maven.settings.Profile@15c0fc
profile is org.apache.maven.settings.Profile@30ff35
profile is null
profile is org.apache.maven.settings.Profile@c30d65

Fixed in r690610 on branch, merged to trunk in r690611
