I have the same xcode version and can't reproduce the issue. Can you tell me exactly the steps you follow to get the error and also the version of MonoDevelop and MonoTouch that you're using?
Comment 2 Alan McGovern 2011-08-24 09:24:38 UTC
By any chance do you get this exception when XCode crashes? The only time I managed to get this exception was when XCode crashed on startup. Right now my suspicion is that if XCode crashes at just the wrong moment, MonoDevelop will get this error and report it.
Comment 3 Alex Soto 2011-08-26 11:34:10 UTC
yest that happened when xcode crashed :) also Xcode has been a little crashy  in this betas, im on Beta 6
Comment 4 Alan McGovern 2011-08-26 11:36:04 UTC
Perfect. I've added some extra error handling so when Xcode does crash like this, you'll get a slightly more useful error message. When Xcode stops crashing at the drop of a hat this issue will vanish completely ;)

Marking this as resolved, thanks for the report!
