Fatal Error when displaying "My" pictures for a username with "ö" in his name ("ötek")


I went Photo page. Default it showed all pictures uploaded by other users. Then I click on tab to see my pictures (I have no pictures), I get following fatal error:

 Fatal error: Call to a member function getGUID() on a non-object in /srv/disk2/1185896/www/myownsite.com/mod/tidypics/pages/photos/owner.php on line 25

The username which this problem had is "ötek". So URL is


I change the username to "otek" now I have no problem with TidyPics. To me seem that TidyPics username handling not compatible with Elgg usernama handling.

I am with:  Elgg 1.8.9 and Tidypics 1.8.0 rc1.

Thank you.
