Ability to run Nuance Dragon Naturally Speaking 11.5 broke with wine 1.5.13

[Henri Sivonen]

Steps to reproduce:
1) Install 32-bit Dragon NaturallySpeaking 11.5 onto wine on 32-bit Ubuntu 11.10.
2) Move the WINEPREFIX directory to 64-bit Ubuntu 12.04.
3) Install wine1.5 1.5.12-ubuntu0 from the PPA (on Ubuntu 12.04).
4) Launch Dragon with WINEARCH=win32.
5) Use it.
6) Update wine1.5 to 1.5.13-ubuntu0 from the PPA.
7) Launch Dragon with WINEARCH=win32.
8) Downgrade to wine1.5 1.5.12-ubuntu0.
9) Launch Dragon with WINEARCH=win32.
10) Update wine1.5 to 1.5.16-ubuntu0 from the PPA.
11) Launch Dragon with WINEARCH=win32.
12) Downgrade to wine1.5 1.5.12-ubuntu0.
13) Launch Dragon with WINEARCH=win32.

Actual results:
Dragon works on wine1.5 1.5.12-ubuntu0. On wine1.5 1.5.12-ubuntu0 Dragon fails. It starts running and terminates during launch. On wine1.5 1.5.16-ubuntu0, Dragon shows its taskbar icon with the tooltip "initializing…" and goes to a seemingly infinite loop on six of the eight CPU hardware threads. Launching Dragon again on wine1.5 1.5.16-ubuntu0 and then right clicking the taskbar icon caused Dragon to crash with glibc complaining about a double free.

Expected results:
Expected it Dragon to continue to work on versions of wine newer than wine1.5 1.5.12-ubuntu0.

(FWIW, the weird steps 1 and 2 were there, because the Dragon installation wouldn’t succeed on Ubuntu 12.04 initially due to https://www.codeweavers.com/support/wiki/linux/faq/ubuntu1204 )

And for clarity, downgrading to wine 1.5.12 makes Dragon work again, so this is clearly a regression introduced in wine 1.5.13.

Can you file a bug in bugs.winehq.org ? This doesn't seem like a ubuntu specific bug, so they probably want to be made aware of the regression. I'll can link the bug to the launchpad bug when you do.
