Did you see a stop sign? In any case don't paste logs, backtraces or any huge chunks of text in comments. Removing applications files like login.cab is not an option, you need to workaround mshtml issue and try with all files present. Otherwise removing it potentially invalidates your report.
Login.cab is only related to login page. I can assert that it is not linked at all to this bug (it did not exist in an earlier version of Skype). By the way, by passing /legacylogin parameter to Skype, you get exactly the same problem, without deleting login.cab.
