Trace mono

When running winecfg on an empty prefix, wine asks to install Mono and Gecko.

When clicking "Install", the download progresses halfway, and then crashes,
with the attached backtrace. I have no such problem when using wine 1.5.7.

The gecko install has the same problem. Though, usually, 1 of the 2 is
installed successfully.

Steps to reproduce:
mkdir /tmp/wine
WINEPREFIX=/tmp/wine ./winecfg

Click "Install"

Output on terminal:
$ WINEPREFIX="/tmp/wine" ./winecfg
