[issue2332] Internal error in HGwebdir raw-rev for one specific status.

[Ton]

New submission from Ton <tcplomp at gmail.com>:

I have one specific changeset that causes HGWEBDIR and HGWEB to throw an
'internal server error' on Windows and on Linux.

Here's the log from the error-hg.log for an apache serve on Linux:

A new commit allows me to read the raw-rev of tip, but this specifc revision
is not traceable via raw-rev. I have tried using hg verify to fix this but
that doesn't work.
