[pkg-wine-party] Bug#756571: Loops: modify_ldt: Invalid argument; err:module:find_forwarded_export ... for 'krnl386.exe16.MapLS'

Package: wine
Version: 1.4.1-4
Severity: normal
Tags: upstream

Dear Maintainer,

    * What led up to the situation?

After 57 days of uptime, I rebooted and picked up a new kernel (there 
were several kernel updates since early June).  However, I was unable to 
start Notes7 under Wine.  The result is that the program looped after 
generating these messages:

p11-kit: couldn't load module: 
/usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: 
/usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: cannot open 
shared object file: No such file or directory
modify_ldt: Invalid argument
modify_ldt: Invalid argument
modify_ldt: Invalid argument
modify_ldt: Invalid argument
modify_ldt: Invalid argument
err:module:find_forwarded_export module not found for forward 
'krnl386.exe16.MapLS' used by L"c:\\windows\\system32\\KERNEL32.dll"

I'm pretty sure the first of these is irrelevant.

    * What exactly did you do (or not do) that was effective (or
      ineffective)?
    * What was the outcome of this action?

Web searching for terms in the final error message were unenlightening. 
  Eventually, I was lead to a launchpad bug 1327532[1] and a Linux 
Kernel Mailing List discussion[2].  I was able to confirm that setting 
ldt16 to 1 resolved the problem and allowed Notes7 to start.
     # echo 1 >  /proc/sys/abi/ldt16

 From the linux-image-amd64 change log I saw that these two patches were 
included in the kernel on 29 Jun 2014 (linux (3.2.60-1) wheezy; 
urgency=medium").  I installed this kernel on July 7th.

     - [amd64] modify_ldt: Ban 16-bit segments on 64-bit kernels
     - [amd64] modify_ldt: Make support for 16-bit segments a runtime option

Eventually, I found Wine bug 36664[3] and FAQ-10.22[4].

The diagnosis was made difficult because my error message was unusual in 
containing "find_forwarded_export" and my program is a 32-bit 
application.  Apparently, even some 32-bit applications make use of 
16-bit DLLs or functions.
