> In op_client.c, the function axis2_get_transport_from_url() is used to analyze the prefix
to the URL.  If the URL is malformed and does not contain a colon, the scan runs off the end
of the url string.
> The loop that reads:
>     start = url;
>     end = url;
>     while (end && (*end) != ':')
>         end++;
> should read:
>     start = url;
>     end = url;
>     while ((*end) && (*end) != ':')
>         end++;
> I'll admit to coming across this by inspection while tracking another problem.  I have
not actually forced the seg fault, as the loop will usually find a colon somewhere in memory
and return a very large transport string.
