help in debugging

[Ioannis Nousias]

Hello Wine developers,

I've decided to see what causes floAt's Mobile Agent[1] to fail with wine

I checked the wine developers' cheatsheet to help me debug the 
application, but I'm lost.

The application installs but with some error:
"C:\Program Files\Fma\sframeword\helper\BramusICQ.dll
Unable to register the DLL/OCX: LoadLibrary failed; code 126
Module not found."

I click "ignore" and the installation continues. When I try to execute 
the installed binary "MobileAgent.exe" it fails.

I invoke it like this:

WINEDEBUG=+seh,+relay WINEPREFIX=/tmp/winetemp wine MobileAgent.exe

no error messages are produce by the app itself.

on wine's debug log I see the following, just before winedbg starts:

this is not the first "trace:seh". Relatively early in the call stack 
there is this:

flags=2
trace:seh:__regs_RtlUnwind handler at 0x602b5400 returned 1
ffffffff (invalid)) ret=6033e95f

which looks suspicious to me.

Am I on the right track? Unfortunately I'm not familiar with windows API 
or wine's underlying architecture. I need some guidance please :) I'm an 
experienced C/C++ programmer.

thanks
