ghostscript version mismatch in 9.05~dfsg-6.2_amd64, "/usr/lib/cups/filter/foomatic-rip failed"

[gene]

This is funny and weird.
I have already reported it here +bug/1168487 for Linux Mint. Then added Debian and "Linux Mint" turned into Ubuntu. And I can no longer add LMDE, since Linux Mint is not available. What kind of freaking magic is this???? Since this is important and might affect printing capabilities I am dubbing it here:

I am running the latest UP 6 LMDE freshly installed, the mate edition. This is a wonderful distro and I am very fond of it , I should admit .
However I found a weird bug in the ghostscript package

2) problems when trying to print, run gs,ps2pdf, atril (to view a postscript doc)
3) getting this:
a) cannot print with cups (brother hl-2230),
b) cannot view postscript files nor run gs/gv, nor ps2pdf utility getting the versions mismatch:

 ghostscript: gs: Interpreter revision (871) does not match gs_init.ps revision (905)
c) when running "gs --version" or "ghostscript --version" get 8.71, which is wrong, since 9.02 is installed according to dpkg-query

4) Expecting to not have the problems above
5) The problem happens all the time
6) possible way to reproduce is:
a) install the latest lmde 201303 (not the rc version)
b) try adding and using a printer --> it won't
c) try running gs/gv or viewing a postscript with gv or atril/evince, they won't
d) try ghostscript --version and get 8.71, which is wrong, since 9.05~dfsg-6.2 is installed.

More info:

I started noticing some weird issues first with cups. I try to add a printer (brother HL2230) and from the past experience I know which ppd file would work with it (it did with my previous Ubuntu 10.04). Everything goes well until I get to print something, it simply won't. I try different ppds and configs. Nothing helps. Although cups debugging is enabled, the logs won't give me much clue, and I see that cups-admin would say something like "cups-filter error". I try upgrading cups and cups-filters using the sid repos, it won't help either.
Interestingly and weirdly though, I got two other machines running lmde fully updated without any cups problem -- I can print from them just fine.

There is one difference though, lmde was installed before the Update Pack 6 and then updated to it. It gives some clue, but not much, until I try viewing a postscript file. Atril (a mate-document-viewer) says it can't. What???? Then I try postscript tools like ps2pdf, gv they all fail, saying that there is problem in the gs_init.ps file. I do

gs --version and get "8.71"

 What??? I thoroughly check and see that there is only dfsg-6.2_amd64 installed, the gs_init.ps wants of course 905. Hence the versions mismatch. . I try reinstalling it, purging and removing the apt archive, it would insist on the "8.71" version. I check the other lmde machines and see they are using the same 9.05~dfsg-6.2_amd64 version. The I notice that it's they also have an earlier version 9.05~dfsg-6_amd64 in the apt archive.

So I guessed that there might some incorrect configurations when 9.05~dfsg-6.2_amd64 are installed afresh. So I add the sid repos to upgrade to 9.05~dfsg-6.3_amd64 and lo and behold this fixes it!

Hence my WORKARAOUND:
upgrade to ghostscript and ghostscript-{-x,cups} 9.05~dfsg-6.3_amd64 that is now in Debian sid by adding in /etc/apt/sources.list:
#sid repos
deb http://http.us.debian.org/debian/ unstable main contrib non-free

Also couple of things I tried before and failed:
1) Since I had texlive-full installed I suspected it was a culprit. Removed it, and gs version was still 8.71. So I add some (not all) packages later.
2) Tried to edit gs_init.ps file to match 871 to please ghostscript, it wouldn't work anyways with some other errors being thrown at me.

Not sure where does ghostscript binary takes its version (I didn't find anything in /etc/ghostscript as well as in my ~ dir) , there must have been a file that got overwritten only when upgrading to 9.05~dfsg-6.3, and apparently would not when going 9.05~dfsg-6_amd64-->9.05~dfsg-6.2_amd64
