[multiarch] easy fix for interarchitectural package conflict?
summary: jessie/sid:amd64 box must install an i386 package which depends on libgif4:i386, but
- libgif4:i386 conflicts with libgif4:amd64
- important apps depend on libgif4:amd64

As detailed @ http://forums.linuxmint.com/viewtopic.php?f=190&t=164522 I am forced to run a 32-bit java plugin (F5 Network Access Plugin) on a 32-bit firefox on an otherwise 64-bit (and up-to-date) LMDE box:
me@it ~ $ uname -a
Linux it 3.11-2-amd64 #1 SMP Debian 3.11.8-1 (2013-11-13) x86_64 GNU/Linux
me@it ~ $ cat /etc/debian_version
jessie/sid
me@it ~ $ inxi -r

As detailed @ https://lists.debian.org/debian-user/2014/05/msg00243.html I am now able to run the 32-bit firefox-3.6.28 on the box. However, when I try to install the F5NAP on the running firefox-3.6.28, I currently get
LoadPlugin: failed to initialize shared library /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so [/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so: wrong ELF class: ELFCLASS64]
followed by similar errors, followed by install failure. To fix this, I try to install an i386 version of IcedTeaPlugin.so as follows (noting the Mint-iness of a tool used):
me@it ~ $ apt contains $(which apt)
mintsystem: /usr/local/bin/apt
me@it ~ $ apt contains IcedTeaPlugin.so
icedtea-7-plugin:amd64: /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
icedtea-6-plugin:amd64: /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
me@it ~ $ sudo aptitude -s install icedtea-7-plugin:i386

There seem to be 3 ways to solve my problem:
1. (easier) remove libgif4:amd64, and hope that's icedtea-*-plugin's only dependency conflict.
2. (problematic) wait for the maintainers to fix the conflict between libgif4:amd64 and libgif4:i386 .
3. (harder) fix the (seemingly nonsensical) conflict between libgif4:amd64 and libgif4:i386 .
Can I remove libgif4:amd64 ? Not unless I want to remove Emacs and LibreOffice (et al), which I don't:
me@it ~ $ sudo aptitude -s remove libgif4
The following packages will be REMOVED:

Option 2 seems unacceptable at this point: I can't telework without the VPN enabled by the F5NAP, and getting on the physical LAN would be *very* difficult at the moment. But perhaps there are currently elsewhere versions of libgif4:* without interarchitectural conflict? If so, how to access them?
Which seems to leave option 3: is there a way that *I* (a debian packaging newbie) can resolve the conflict between libgif4:amd64 and libgif4:i386 with minimal pain? I very much need to get back to Real Work(tm). Apologies if this is a FAQ, but I didn't see any information on this topic targeting a package end-user while either casually DDGing or a less casual read of https://wiki.debian.org/Multiarch (which seems more targeted to package maintainers). Feel free to pass pointers to Fine Manuals; I will cheerfully RTFM.
your assistance is appreciated, Tom Roche <Tom_Roche@pobox.com>
