Hi,

thanks for the report.

here's the fix:

Index: ps/ps.map/do_plt.c
===================================================================

 	    break;
 
 	case 'E':		/* EPS file */
-	    if (sscanf(buf, "E %d %lf %lf %lf %lf %s",
+	    if (sscanf(buf, "E %d %lf %lf %lf %lf %*s",
 		       &masked, &e1, &n1, &scale, &rotate, name) == 6) {
 		if (masked && after_masking)
 		    continue;

sscanf()'s %s stops scanning the buffer at a space so just the
first part was picked up. I'm a little rusty on my formatting
codes but I believe %*s will keep going to the end of the line.
Seems to work anyway. We are rather lucky that the programmer
had the foresight to make the freeform filename the last
parameter of that line; good practice pays off!


@devs: is svn open for commits or should we wait for the SSL
cert renewal to make its way through the system?
