The string Selector name found in current argument registers: isEqual: in the crash report is actually coming from HockeySDK and shows the last selector name objc_msgSend() was trying to call. It is identical to OS X showing the following string in their crash reports: objc_msgSend() selector name: isEqual:.
We’ll improve this message in our SDK and also see what we can do in the backend for current incoming messages.
So the crash is not caused by HockeySDK!
The reason for the crash is, that objc_msgSend (thread 10 frame 0) was trying to call isEqual on an invalid object, hence the exception type SIGSEGV (See http://en.wikipedia.org/wiki/Segmentation_fault ). This was triggered by [NSButtonCell _currentTitle] in frame 4.
So you might want to check your table views and cells memory management. Especially when you assign a title to an NSButtonCell.
