--- Comment #5 from joaopa jeremielapuree@yahoo.fr 2011-05-27 12:47:15 CDT --- Use an up to date Wine: now it is wine 1-3-20 What is the name of your application?
And to get a valid backtrace: go to the directory of the application cd .wine/drive_c/Program File/repertory of the application
then
wine my_application.exe &>$HOME/log.txt
and then attach to wine bugzilla the file log.txt (don't forget to give the correct mime type in bugzilla)
