I received more e-mails from people reporting this segmentation fault in my
program. I know what you are thinking ("it is a bug in your program"), but just
look at the code:
---------------------------------
void
read_plugins (KTPluginList *plugin_list)
/*
Input:
	-
Output:
	plugin_list	- The plugins are added to this list.
Returns:
	-
Description:
	This function reads the plugins from the plugin directories and adds them to
	plugin_list.
*/
{
	char	*home_dir,
		*local_plugin_dir;
	int	local_plugin_dir_len;
	
	read_plugin_dir (PLUGIN_DIR, plugin_list);
	home_dir = (char *)getenv("HOME");
	if (home_dir != NULL)
	{
		local_plugin_dir_len = strlen(home_dir)+strlen("/"LOCAL_PLUGIN_DIR);
		local_plugin_dir = keytouch_malloc(local_plugin_dir_len+1);
		strcpy (local_plugin_dir, home_dir);
		strcat (local_plugin_dir, "/"LOCAL_PLUGIN_DIR);
		read_plugin_dir (local_plugin_dir, plugin_list);
		free (local_plugin_dir);
	}
}
---------------------------------

I only received reports from people using an AMD64.
