What does myForm::play_file(QString) do?

[safknw]

What does myForm:lay_file(QString) do?

Play the file specied as argument in mplayer in slave mode.

[jacek]

Play the file specied as argument in mplayer in slave mode.

It calls some function from Qt which leads to a crash. Do you know which one? If not, compile Qt in debug mode and try again (make sure you have "CONFIG += console" to your .pro file and check whether there are any messages on the console).

[georgie]

if it crashes at a point when you are accessing a file, did you make sure to change these filenames to windows format too? or is it a user input/file dialog kinda situation
