Reproduction sample

Description of problem:
Since last update, ghostscript does not properly render certain pdf files.
 from 8.15.2-9.11.el5, to 8.70-6.el5

Version-Release number of selected component (if applicable):
8.70-6.el5

How reproducible:
Please see attachment. Renders fine in 8.15.2-9.11.el5 and 9.01-1.fc15, corrupted in 8.70-6.el5 and 8.71-16.fc14.x86_64.
Comment 1 Tim Waugh 2011-03-23 16:26:20 UTC 
Confirmed.  The spacing of the lettering is completely out.

Comparison of -dDEBUG output between 8.70-6.el5 and 9.01-1.fc15 shows that 9.01-1.fc15 (which gets it right) has extra FAPI debugging output:

FAPIhook DIN-LightAlternate
Trying to render the font Font DIN-LightAlternate with FAPI...
Font DIN-LightAlternate is being rendered with FAPI=FreeType
[...]
FAPIhook DIN-LightAlternate
Font DIN_LightAlternate is mapped to FAPI=FreeType
Comment 2 Tim Waugh 2011-03-23 16:31:59 UTC 
Trying the Resource/Init/gs_fapi.ps from 9.01 as a drop-in replacement has no discernable effect.  Will need to try bisecting between the two revisions to see when/why/how it was fixed.
