Bug#774759: [pre-approval] unblock: ghostscript/9.06~dfsg-2
Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock
Dear RT,
I'd like to get the patch for #732440 included in Jessie. The bug was
reported three independent times and is a premature abort in Ghostscript
processing. The patch that fixes that bug was included in upstream's
9.14 version and can be directly cherry-picked on top of 9.06~dfsg-1 as
currently in jessie.
Here goes the proposed changelog:
ghostscript (9.06~dfsg-2) unstable; urgency=medium
* Add patch cherry-picked upstream to fix /typecheck error in /findfont
(Closes: #732440)
The cherry-picked patch as well as the full debdiff are attached.
TIA, cheers,
OdyX

+Bug 695031: don't assume we can read a font file
+
+When we scan system fonts, we were assuming fonts found would be in a format
+Ghostscript understands. This is not necessarily the case.
+
+So put the minimal parsing call to get the font's name in a stopped context,
+so we can skip the file it's not an understandable format. And clean up the
+stack in the event we try such a file.
+
+No cluster differences.
