As expected, nobody wishes to dig into obscure X11 issue.

You may try the attached patch. I do not consider it as unambiguous 
improvement since almost all errors are swallowed due to requirement to 
interpret viewer command using shell. The same approach settled on 
`browse-url' after several fixes, but there at least wrong executable 
name may be reported.

I suspect that you faced the bug working on another issue, so you do not 
really suffer from it.
