LO - 4.1.1-RC2 report-builder problem

Hello,
I tried to run a report based on a MySQL-Database view. It runs perfectly
fine on LO 3.6.7 (OS is Linux-Debian-Wheezy). On 4.1.1-RC2 I get the error
"An exception of type com.sun.star.lang.WrappedTargetException has been
detected".
Thanks for dealing with the problem...
Regards
H.S.
