backtrace when WineExplorer crashes.

BrainExplorer2 can be installed, and can be started.

The first thing it will ask you is to download up to for atlases of size 30-110
MB. For testing, it is sufficient to download the smallest.

When the atlas is downloaded, and should be loaded, the BrainExplorer2 crashes
(see attached backtrace). The crash can be avoided when starting BrainExplorer2
is prefixed with

WINEDEBUG=warn+heap

This is reproducible and happens when any of the 4 atlases is selected. It
happens also on different wine versions (1.6.2, 1.8-rc3) and also when
WINEARCH="win32" is set.

I'm surprised by this "hack", because I thought WINEDEBUG would only affect the
debugging, and not the memory management itself.
