Seg Fault - Creating new wiretap type

[Alex Lindberg <alindber () yahoo com>]

I am trying to add a new filetype to wiretap to allow for the reading of my custom file type, a pure text file.  When 
trying to read the first line during the initial myfile_open routine, the file_gets or file_read fail with a 
segmentation fault. If I do my own fopen for the filename, all is good, but when using wth->fh, it fails.  I have 
copied the format found in other wiretap/*c files and don't see my error.
If the length of the buffer == 1, then the calls work, if the buffer length is anything greater than 1, it fails.  The 
same form when using a private fopen to the same file works just fine.  The SIGSEGV happens during the read command.
int myfile_open(wtap *wth, int *err, gchar **err_info _U_) {
 guchar *input_line = NULL; input_line = g_malloc(1000*sizeof(guchar));
 if((file_gets(input_line, 1000, wth->fh)) == NULL) {  printf("Error on file_gets 0x%0x\n",file_error(wth->fh));  
return FALSE; }
As always, thanks for your help with this.Alex Lindberg
