The attached image is shown as expected in Okular 0.16.1 (Ghostscript backend (gs 9.05), 32-bits).

What Ghostscript version do you use?

Comment 4 Antonio Rojas 2013-03-06 07:41:25 UTC

This is caused by the ghostscript 9.07 update, which breaks libspectre:

Not much we can do at the Okular level, i'll try to have a look at the spectre sources and see what's going on.

Comment 6 thomas.gastine 2013-03-07 10:52:45 UTC

Indeed, downgrading to ghostscrip 9.06 works. In addition, it seems that a simple eps2eps on the figure is enough to make it visible with okular 0.16, gs 9.07.
