To view PDF files, gv uses the obsolete pdf2dsc.ps file, which was present in ghostscript up to 10.04, but removed in ghostscript 10.05.0~dfsg-1. So one now gets an error: Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push Dictionary stack: --dict:759/1123(ro)(G)-- --dict:0/20(G)-- --dict:85/200(L)-- Current allocation mode is local Last OS error: No such file or directory ------------------------------------------------------------ in the terminal and an error window saying that the execution of "gs ... pdf2dsc.ps -c quit" failed. The PDF file can be viewed, but the page numbers on the left pane are missing.
