Joey, please see RecentChanges and note that this is my second bug report,
because the first was unsuccessfully (bad characters in post title?).
Could you please tidy it up?

> I've fixed that and the bug that caused the dup.

>> Thanks a lot! :)

I've just upgraded my ikiwiki from version 2.11 to the latest version 2.15.
I use my own rebuilt ikiwiki package for Ubuntu Gutsy box. Now I can't rebuild
all my ikiwiki pages, because of the following bug:

    ptecza@anahaim:~/blog$ ikiwiki --setup ikiwiki.setup --getctime --verbose
    [...]
    scanning post/2007/12/09/pink-freud-w-cafe-kulturalna.mdwn
    ikiwiki.setup: Insecure dependency in mkdir while running with -T switch at /usr/share/perl5/IkiWiki.pm line 355.
    BEGIN failed--compilation aborted at (eval 5) line 151.

I have a write permission to the ikiwiki destination directory:

    ptecza@anahaim:~/blog$ ls -ld /var/www/blog/
    drwxr-xr-x 2 ptecza ptecza 4096 2007-12-17 10:48 /var/www/blog/

I've read ikiwiki changelog for the previous releases and unfortunately
I can't see any related entries. Any ideas?
