Hi Well, my Grade II problems continue. I've found a way to guarantee a crash in Orca. I don't mean a lock-up, I mean Orca crashes. Ironically, Will, it's a line in your messages that does it. When I have grade II turned on, the following line of text causes Orca to die: for exceptions coming from liblouis -- I need to consult with Eitan Running orca in a terminal, I get the following output from it when the crash happens: jschmude asmodean:~$ orca ** (orca:29502): WARNING **: Trying to register gtype 'WnckWindowState' as flags when in fact it is of type 'GEnum' ** (orca:29502):

moment. It's guaranteed. Several lines in that stack trace also cause the same exact crash to happen although with slightly different memory addresses naturally. Think maybe I'll leave grade II off for now. I can't have Orca dying on me at random intervals. Any idea what's going on here? Any other info I can provide about this crash?
