Uh, removing the indexdb does fix it when rendering that one file
manually, but not when rebuilding the whole set of page -- even rm -rf
.ikiwiki doesn't help:

    [...]
    scanning ikiwiki/pagespec/sorting.mdwn
    scanning ikiwiki/pagespec/po.mdwn
    scanning ikiwiki/subpage/linkingrules.mdwn
    building render_locally
    building abac.mdwn
    *** stack smashing detected ***: /usr/bin/debugperl terminated
    Aborted

render_locally is simply copied, and abac.mdwn is the first page to be
built.

Regards,
 Thomas
