This is a side effect of the fix for bug 512096. Part of this fix had to be reverted due to performance issues. When a crash occurs during an upgrade, the files extracted from the archive during the last 30 seconds (default system value) before the crash are 0 bytes excepted the control files.
Thanks for your report.
