Re: Problem executing program against pixbuf 2.2.4 library

[Struan Bartlett <struan praguespringpeople org>]

Hi,

Nobody has replied about my problem using the pixbuf 2.2.4 library, but
the problem hasn't gone away. Perhaps this means I'm the only person with
this problem with the 2.2.4 pixbuf library. Or perhaps it means that
nobody else is using the 2.2.4 pixbuf library.

If you're using the 2.2.4 pixbuf library successfully, please could you
let me know?

Kind regards,

Struan Bartlett.
