--- Comment #18 from Vincent Povirk madewokherd@gmail.com 2008-07-11 09:30:32 --- Created an attachment (id=14727) --> (http://bugs.winehq.org/attachment.cgi?id=14727) patch that happens to prevent the crash
What seems to be happening is that Acrobat creates a dialog, checks the filter combo box to see which item is selected (probably so it can decide whether to grey out its settings button. Wine currently reports that no item is selected because the combo box is empty, and I found that populating the dialog a little earlier made this work. I'm not sure what all the consequences of this change are so for now I'm not trying to get the patch committed.
