Hi,

in current GIT error occurs because mshtml tries to release a faulty
SupportErrorInfo object. Backtrace is:

wine: Unhandled page fault on read access to 0x0445535d at address 0x7d18440e
(thread 0009), starting debugger..
=>0 0x7d18440e SupportErrorInfo_Release+0x2e(iface=0x86ef7c)
[/home/markus/wine/wine/dlls/mshtml/htmldoc.c:1438] in mshtml (0x0032cf54)
  1 0x00407500 in cakemania2 (+0x7500) (0x0032cf7c)
  2 0x0040762e in cakemania2 (+0x762e) (0x00000000)

Error occurs here:

    HTMLDocument *This = SUPPINFO_THIS(iface);
    return IHTMLDocument_Release(HTMLDOC(This)); <- ERROR

And here some debug messages that show that This->lpVtbl is the culprit (access
violation and this pointer refer to 0x4455355):

fixme:mshtml:SupportErrorInfo_Release debug iface=0x86ef7c
fixme:mshtml:SupportErrorInfo_Release debug This=0x86ef2c
fixme:mshtml:SupportErrorInfo_Release debug lptvtbl pointer is 0x4455355
