Or, in other words: Gnucash trunk is currently broken as it doesn't implement 
the necessary GUI usage for aqbanking5. I just changed the gnucash code in 
r19359 to at least *compile*, but it won't work for the setup. I'm sorry for 
that.

The normal online banking usage still works, as the aqbanking4-style GWEN_GUI 
implementation of gnucash still seems to be sufficient for those operations. 
But the setup doesn't work. At the time when I committed r19359 I didn't 
understand that yet, but now it is clear, and I'll add an appropriate trace 
output in a minute.

Again: GnuCash trunk compiles with the newest aqbanking5 (beta releases or 
from SVN), but in contrast to compiling with aqbanking4, not all features will 
work for now. Specifically, pressing the "Start Aqbanking wizard" button 
currently does nothing and is not yet implemented. The other operations 
probably continue to work.

(Any gnucash older than trunk doesn't compile with the newest aqbanking5 
anyway, so the issue doesn't arise if anyone deals with older gnucash.)

Regards,

Christian
