--- Comment #9 from Anastasius Focht focht@gmx.net --- Hello julien,
well the backtrace is not very useful. Always attach both, the backtrace _and_ full console output up to the crash.
If the database functionality is not working it could due to missing ADO.NET dependencies (mdac28, jet40 via winetricks).
Regards
