Issue #3784 has been updated by Hiroshi Nakamura.


Enrico, sorry for late reply.

Is it still occurs with the newer 1.9.2 version? (1.9.2p180 is the latest released version) Would you please try 1.9.2p180 or development version at trunk (if possible) and show us ~/Library/Logs/CrashReporter or /Library/Logs/CrashReporter for more investigation?
