Text widget dying

[Shippy! <shippy ladron cs nmt edu>]

For some reason, this function is causing my
program to die:

void log(log_type type, char *message, ...)
{
   GdkColor color;
   va_list args;
   char fmtmsg[MAX_STR_LEN];
   char *logmsg;
      
   memset(&color, 0, sizeof(color));
   switch(type)
   {
      case LOG_ERR:
         color.red = 0xE665;
         break;
      case LOG_RCV:
         color.blue = 0xCCCC;
         break;
      case LOG_SND:
         color.green = 0x7FFF;
         break;
      default:
         break;
   }

   va_start(args, message);
   vsprintf(fmtmsg, message, args);
   va_end(args);
   
   /* Hide the passwords */
   if(strncmp(fmtmsg, "PASS", 4) == 0)
   {
      logmsg = malloc(15);
      strcpy(logmsg, "PASS ********\n");
   }
   else
   {
      logmsg = &fmtmsg[0];
   }
/*
   gtk_text_freeze(GTK_TEXT(log_win));
   gtk_text_insert(GTK_TEXT(log_win), NULL, &color, NULL, logmsg, -1);
   gtk_text_set_point(GTK_TEXT(log_win),
gtk_text_get_length(GTK_TEXT(log_win))$
   gtk_text_thaw(GTK_TEXT(log_win));
   gtk_adjustment_set_value(GTK_TEXT(log_win)->vadj,
                            GTK_TEXT(log_win)->vadj->upper);
*/
} 


It's the function I use to log FTP data. Somewhere
in the commented-out area, something is causing my
program to die. Here's an example backtrace:

What's interesting is that my program is multi-threaded
I thought maybe I needed to compile gthread in, but when
I do that, I get a bunch of other problems.

I'd like to also note that the program works wonderfully
on my computer. Also, I'm having other problems after I
actually get connected to a host and try to navigate around.
I'd like to figure this problem out first, though before
I try and figure that one out. Could this machine just
be messed (because it works fine on my machine) or is
there something I'm not doing right?

Thanks in advance,
