Yesterday I did a routine update of my SL 5.5 system which included an ImageMagick upgrade. I then found that when doing 'convert's' from postscript to other formats, e.g. convert xxx.ps xxx.png , the process failed with this diagnostic output: ---------------------------------------------------------- [2073]cedar /home/rosmond/gnuplot: convert xxx.ps xxx.png Error: /undefinedfilename in (72x72) Operand stack: Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push Dictionary stack: --dict:1154/1684(ro)(G)-- --dict:0/20(G)-- --dict:70/200(L)-- Current allocation mode is local Last OS error: 2 GPL Ghostscript 8.70: Unrecoverable error, exit code 1 Error: /undefinedfilename in (72x72) Operand stack: Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push Dictionary stack: --dict:1154/1684(ro)(G)-- --dict:0/20(G)-- --dict:70/200(L)-- Current allocation mode is local Last OS error: 2 GPL Ghostscript 8.70: Unrecoverable error, exit code 1 convert: no decode delegate for this image format `xxx.ps'. convert: Postscript delegate failed `xxx.ps'. convert: missing an image filename `xxx.png'. ------------------------------------------------------------------- I did 'yum downgrades' of ImageMagick.i386 and ImageMagick.x86_64, and this corrected the problem. Has this happened to anyone else? Who else should be notified? Tom Rosmond
