Chris,

When you get time, please try changing:

unsigned cnt = wxDir::GetAllFiles( GetLibraryPathList()[i], &tmp, wxT( 
"*.mod" ) );

to:

unsigned cnt = wxDir::GetAllFiles( GetLibraryPathList()[i], &tmp, wxT( 
"*.mod" ), wxDIR_DEFAULT | wxDIR_NO_FOLLOW );

and see if that resolves the problem.  It's seems odd to me that it 
works correctly when Pcbnew is run directly from the command line but 
fails when Pcbnew is launched from KiCad.  Are you using a debug build? 
 It may be possible that wxWidgets is trying log something to stdout 
and that is what is actually causing it hang.

I wont be able to look at this until sometime tonight or tomorrow.  I 
plan on enjoying the rest of Fathers Day with the family.  Good catch 
and thanks for the help.

Happy Father's Day to all of you fathers out there.

Wayne
