When using maria_read_log to recover from scratch from the varchar RQG scenario, the tool reported the following:

I can't repeat the problem either with RQG command line or with the given data files.
One can't reliably run maria_read_log on an empty dir as mysqld wasn't started with the --safe-mode option.
However, even while doing that, I don't get the given error.
Note also that my last fix in 5.1 tree regarding "When reopening table during recovery, don't set file length from file sizes as file is not flushed" fixed a symptom identical to this bug.
