--- Comment #1 from mikey abc.mikey@googlemail.com 2007-09-24 06:33:51 --- Created an attachment (id=8192) --> (http://bugs.winehq.org/attachment.cgi?id=8192) trace from steam
Here is the output from a crash.
In this case I managed to circumnavigate the error by loading steam with the -silent flag and then quickly right clicking and selecting games (otherwise it still crashed). This crash occurred after I clicked back on the store tab.
