--- Comment #5 from Mike mrheinheimer@ohmyhead.com 2009-12-29 16:56:00 --- Setting to native gdiplus only in winecfg got me past the initial crash. Now I'm up to the typical LR behavior already reported in several other bugs and on the forum. We can close this one, unless you'd like some more info.
Unrelated: I actually tried exporting a RAW (Canon CR2) to jpg format (without being able to see what I was doing, of course), and it succeeded. I guess all of the problems supporting LR are entirely within the gui libraries.
Thanks for the quick response! I'm happy to collect more information for whomever takes on the challenge of supporting LR.
