I'll look at this shortly, thanks for the report. As a suggestion, if
you have problems with UBIFS and going to send a bug-report, try to
enable debugging, reproduce the problem and send dmesg. With debugging
enabled it prints more useful information and makes it easier to
identify and fix the issue.
