Hi, I am trying to diagnose a crash report that appears to be related to ShareKit, and would appreciate some advice.
The crash is reported from a thread that appears to be calling a ShareKitHelper XPC service. The main thread appears to have spun off that thread to determine what sharing options or accounts might be available. My customer reports that the crash happened when he opened the Preferences window in my app. Based on the crash report, it looks more like the crash was the result of right-clicking in an NSTextView. I still need to find out whether he can reproduce this crash. Since I never explicitly call ShareKit or use Share Sheets, it feels like this must be a bug in Mac OS X. Relevant parts of the crash report are below. Any troubleshooting or debugging advice would be appreciated. Thank you.
