The template for a new directory ( emtpydir ) does not exists. I found a dodir in kdebase-3.0-r1, but the directory is not created. Mayby because I have remerged the kdebase-3.0-r1 package ?!
Dan -- sounds like you need to create a directory or two in pkg_postinst() to prevent the "empty directory disappears on remerge" bug.
I've done as suggested. Committing kdebase-3.0-r3, bug fixed.
