NetBSD beast 6.1.1_PATCH NetBSD 6.1.1_PATCH (PCIPAE) #2: Wed Oct 23 19:09:00 
EST 2013  build@test:/usr/src/sys/arch/i386/compile/obj/PCIPAE i386
>Description:
Whilst in KDE if you open konsole and export LANG=en_AU.UTF-8 (or any other 
UTF-8 variant) or LANG is exported in your shell profile.

Then attempt to start kmail from the konsole and the process freezes.

If LANG is not set it will run (you receive an error about klocale though.)

The problem that I've found is that it calls setlocale and the libkmailprivate 
init functions are called and these call setlocale again so it is recursive as 
described in the following backtrace:

>How-To-Repeat:
Refer to above.
>Fix:
I've found that changing libkmailprivate fixes the problem, I patched the 
function that was called after libkmailprivate init function so as not to call 
i18n and subsequently calling set locale again,  I've found that the error 
message printed on the terminal after starting kmail about klocale is gone also.

Here is the patch:

I hope this is the cause of the problem and not setlocale.
