Commented Unassigned: Sys.WebForms.PageRequestManagerServerErrorException [27554]

I get the error belowe when ScriptMode is set to Release.

> Error: Sys.WebForms.PageRequestManagerServerErrorException: Script entries not loaded yet.

This error occurs on version 7.1002.0 and greater. In a page I am adding AccordionPanes programmatically, but it always shows that error.
Comments: Nice, so in other words - fix broken feature -> disable it? :-)
