I recently stumped across Fossil and got really interested by its concepts. In order to play with it, I installed Debian unstable's fossil ([dcf7bf4455] 2009-12-23 20:27:15 UTC), cloned the fossil repository, opened a working directory, cd'ed into that and issued "fossil info 1234" which resulted in the following crash:

<verbatim>
$ fossil info 1234

More can be supplied on request.

I built a local version [06b964a0cf] which shows the same problem.

Note: The problem only occurs when trying to (invalidly) specifying an artefact id with 2 to 4 digits.
