It looks like it is crashing while opening the directory browser. I'm no wine expert but "ViewModeToListStyle ViewMode 0 not implemented" sounds like it fails to convert the dialog LDCad asks for to the local way of presenting things.
As a last resort you could manually edit main.cfg to set the location of the LDraw library to avoid the dialog.
But it might still crash when trying to open or save files, as those are similar dialogs.
