Also, on Mac OS X, both 32- and 64-bit:
IDL> print, !version
{ x86_64 darwin unix Mac OS X 7.1 Apr 21 2009 64 64}
IDL> a = dialog_pickfile(default_extension='txt',filter='*.txt')
Segmentation fault
IDL> print, !version
{ i386 darwin unix Mac OS X 7.1 Apr 21 2009 32 64}
IDL> a = dialog_pickfile(default_extension='txt',filter='*.txt')
Bus error
