--- Comment #7 from Michael Earl treptoplax@gmail.com 2009-06-20 21:42:34 --- Created an attachment (id=21922) --> (http://bugs.winehq.org/attachment.cgi?id=21922) windebug log of segfaulting City of Heroes updater
(note that this log is quite large, >10M lines uncompressed)
Jeff Z. kindly reviewed and notes that crash seems to be thread 0016, which has some mention of Mozilla.
The updater does display banner ads/text/notices which are probably HTML-rendered; possibly this is related to bug 16794?
