Sharepoint is weird

So, I had an issue today where Document Libraries, only under "My Sites", would not display. They threw a very helpful "An unknown error has occured". Of course this only seemd to happen on My Site Doc Libs, not anywhere else on the portal. To make a long story short, apparently the spsHeader_Personal.ascx file does not like the PersonalProperty tags. No idea why. All the other header files work fine with them. Oh well, word to the wise.
