Fix for tix segfaults on busy dialog

[Chris Carlin]

I ran into a problem where a certain program would crash with a segfault after trying to open a dialog box.

Some investigation lead me to this bug report with at least a partial fix:
https://bugs.archlinux.org/task/33607

It looks like Tix crashes when trying to turn the cursor into a busy cursor, so by short circuiting that the segfault is bypassed.

As the bug report says, "I patched the file inserting a return statement at line 179, so that the tixBusy function returns immediatly."

I made the change on my system and the segfault went away.

Maybe Ubuntu wants to implement this patch? I know it's a brute force solution.
