I agree, especially as simply compiling the regular expression can 
cause the same problem.

I'll gladly have a go at that. not having used gdb before I'm 
wondering if anyone can suggest a tutorial or recipe.

I am using the bundlebuilder that came with Panther's built-in Mac 
Python 2.3. Here's the basic call (the build script has additional 
code to handle the fact that I mix some data files, e.g. sounds and 
html help, in with my modules, but this just copies files into the 
bundle):

inclPkgs = ["RO", "TUI"]
libs = [
        "/Library/Frameworks/Tcl.framework",
        "/Library/Frameworks/Tk.framework",
]
resources = [tuiDir]
bundlebuilder.buildapp(
        name = appName,                         # application name
        builddir  =  ".",                     # dir for application
        mainprogram = mainProg,         # your app's main()
	argv_emulation = False,		# drag&dropped filenames show 
up in sys.argv?
        iconfile = 'TUI.icns',          # file containing your app's icons
        semi_standalone = True,         # make this app self contained.
        includePackages = inclPkgs,     # additional Packages to force in
        libs = libs,                            # extra libraries to force in
	resources = resources,		# extra files or folders to 
copy to Resources
)


Note that this same code also hangs under RedHat 9.2 linux with 
Python 2.3.3. Still, the fact that it runs fine as a pythonw 
command-line app (with GUI) and not as a bundled app is certainly 
suspicious and if gdb will show what's going on, that'll be great! 
I'd sure rather not hack my own version of ftplib.
