wine error output with trace enabled for mshtml and shdocvw

Wine version is todays git pull and build in ubuntu gutsy.

Steps to reproduce:
1. start&login to bbo client
2. click "Help me to find game"
3. click in popup either of submit buttons

result:
program crashes

excepted result:
Software would move to a table to play or observe.

If I use my firefox to access the webpage that is opened to popup I can choose
to play or observer from there. After I press button in firefox game works fine
and I end up to a table.

Reason for crash:
shdocvw crashes because of null pointer in navigate_hlink.

IMoniker pointer is null that is coming from HlinkFrame_Navigate calling
IHlink_GetMonikerReference.

For me it seems like wine is trying to access the content of popup after
closing it. But can't be sure because everything happens too fast.

I couldn't yes solve more about this because I'm not too familiar with wines
code.

I have added a test if moniker pointer is null and output a message with ERR
macro.
