Using my last WebKit nightly download to download the latest nightly, the last two times (download of WebKit-SVN-r34965.dmg and download of WebKit-SVN-r34974.dmg) ".bz2" is appended to file name like this: "WebKit-SVN-r34974.dmg.bz2". After removing the bzip compression using GUI Tar 1.1.1 and/or Untar 1.3.3 I get "WebKit-SVN-r34974.dmg" which is 81.2 MB in size and won't mount, generating an alert "The following disk images failed to mount WebKit-SVN-r34974.dmg not recognize". If I copy the URL (r34974.dmg">http://builds.nightly.webkit.org/files/trunk/mac/WebKit-SVN-r34974.dmg) and download with Interarchy 9.0.1 ".bz2" is not appended and the build mounts normally. The same ".bz2" appending problem happens with Safari v 3.1.2 (5525.20.1)
