There is some kind of caching going on to keep urls available for some time
after a page has been moved or renamed. Maybe thats your problem. The time
period can be set by the TS var expireDays, see realurl documentation.

I found a hint somewhere that this might happen if you create a new page and
save it without having a title set.

There is an additional field named tx_realurl_pathsegment in the pages
table. You can see and change the content of this field in the advanced
page view. Alternatively you can empty the whole tx_realurl_pathsegment
column to get rid of the numbers.

BTW, the order of fields that are used to build up a page path is controlled
via the TS variable segTitleFieldList. By default tx_realurl_pathsegment
has the highest priority. 

I think that it might be helpful if all the fields defined in
segTitleFieldList would be used to determine a page id for a given page
path.

I for my part have another problem with realurl: Under certain circumstances
an "404 page not found error" happens when a page is accessed directly by
url. This happens especially when there is not a single link to that page
within the typo3 fe or when the cache has been cleared shortly before. If
you then navigate to that page using typo3 navigation links (or <LINK ...>)
the page is available via the same page path. It somehow seems as if a page
is available via a realurl page path only after the path has been
constructed from an id at least a single time.
