--- Comment #9 from Indrek efbiaiinzinz@hotmail.com --- 1. Indeed, the tucows installer crash itself is gone but it seems to get in an endless loop, spamming the console with TranslateAccelerator fixme's. 2. Yes, that crash is gone and page load up correctly. 3. After a bit of digging it seems that nsstyle is released too soon (ref reaches zero, causing cleanup) but later on it is used again in a cleaned up state, causing the crash. I don't think my skill is high enough to fix it correctly. I got it to "work" by modding get_nsstyle_attr_nsval (line 482 in mshtml/htmlstyle.c) to return E_FAIL if nsstyle is NULL but this does not fix the issue with the early cleanup which is the root cause.
Perhaps someone with more debugging experience can take a look at it.
