The original didn't crash either. However, it did output this:

(gtktest3:1888): Gtk-CRITICAL **: file gtkfilesystemwin32.c: line
578 (gtk_file_
system_win32_get_parent): assertion `g_path_is_absolute
(filename)' failed

When I commented out the line

gtk_file_chooser_set_filename(GTK_FILE_CHOOSER(dialog),"");

it didn't output any warnings at all. Either way, it didn't crash.

I'm using Windows XP Pro, and my %HOME% variable is not set.

I'm using the precompiled libraries from Tor's page.

Some explanation is in order here. I embellished the original to
make it run as a GUI-only program (no console) because I thought 
you were targeting Windows. As for WinMain, I think command-line 
argument handling using the traditional Windows API is a little 
different. IIRC they have a parseCmdLine function which takes the 
entire command line as a single string and extracts the options 
and arguments from it. As for GTK+, it requires the args in the 
form int*, char***, so I had to use the ones defined by stdlib.h.

hInstance and hPrevInstance are handles to the current instance
and the previous instance of the program (that are running at the
same time), and are also used in the Win32 API.

nCmdShow is basically a boolean -- should we show the window now
or not? Again, something that fits inside the Windows API. I think
GTK+ probably has other ways of dealing with this same issue.

HTH,
