I have a freeware app with crash reporting built in, and every once in a while I get a report of a NilObjectException with the following stack dump:
Sub Delegate.IM_Invoke( Listbox )
this only happens on the Mac. I have not seen this being reported for the Windows or Linux builds of my app. Unfortunately, non of the users have provided any additional data, and the only reason why I’m even getting these reports is because it’s very easy just have the app send the report. I don’t know when exactly this happens, but from the rest of that data that is logged in the report, it appears that this may be happening very soon after the app was launched.
There are probably several hundred users using this app on a semi-frequent basis, and I get a report like this about every other weak. It doesn’t look like this is happening on a consistent level, and I have also never seen this happening on my Mac.
What is weird is that the stack dump doesn’t list any of my methods or event handlers I implemented. I also don’t use any delegates. I.e it doesn’t appear that any code I’ve written is doing anything at the time.
Has anyone seen anything like this before?
