[arch-multilib] Memory access error with gtk

[Harvey]

Hello all,

A recent update brought a weird error with the standard gtk 
filerequester. When I try to use the scrollbars or scroll down in the 
requester with the mouse wheel the complete app (Real Studio 2011 R4.1) 
simply dies with a memory access error. No further error messages, the 
app just vanishes from the sreen. All other functionality of the 
requester is o.k. This has been introduced about a month ago. 
Downgrading lib32-gtk2 to an earlier version does not work as there are 
dependencies for libcups that need lib32-gtk2 in version 2.24.

Any clues? Or at least some tips how I can debug this further?

FWIW: In an archlinux 32 bit installation the app is just working...
