Hello.

We have experienced a problem with FriendlyUrlRewriteProvider.

It sometimes does not work correctly. The same link can be processed one time and cannot be processed another time.

Here is the sample from the log.

Correct processing:

Does anybody experienced already similar problem or have any ideas what is it?
