Error with new "default theme" after upgrade to RC2

[Hugo Habicht]

I get the following errors:

8: Undefined index: thumbnail_href
Datei: E:\Oldieforum\Themes\default\Themes.template.php (eval?)
Zeile: 436

8: Undefined index: selected
Datei: E:\Oldieforum\Themes\default\Themes.template.php (eval?)
Zeile: 435

Upgrade was fine without errors?

Any idea?

Did everything update including your language files?

It's very strange, the error occured only once, the first time entering some adminstrative panels.
Now it works fine without errors:
