I've found a quick fix to this problem. I've simply added a line:

                strncpy(ptr+len, "\0", 1);

just before the mylog line on line 850 of convert.c. I believe this
simply ensures that there is a NULL at the end of the string stored in
ptr. There may be a more elegant way to do this but it seems to work.

Now onto the next fault cause it fails again shortly after this.
Bugger!  :-(
