I'm using the current Subversion HEAD (r3996) and this error apparently happens on any attempt to access a /changeset URL

Looks like you have neither of those options set in your TracIni:

[diff]
tab_width = ...

[mimeviewer]
tab_width = ...

but we should probably default to '8' in this case.

Fixed by r3998.

Thank you so much. I couldn't believe how fast that fix was. In fact my trac.ini had a tab_width = <blank> entry, which I've now set in any case.

was that a newly created env, or because you set it like that by mistake?

Ported to 0.10-stable in r4016.
