League of Legends has been crashing intermittently for me during loading, this problem did not exist prior to updating to OS X 10.9 Mavericks. When it crashes, I receive the crash log below, partially copied here for reference. Attempting to reconnect replicates the crash. Restarting the launcher does not fix the problem and generally leads to the launcher crashing repeatedly. Only remedy I have discovered so far is to restart the computer. Once I've restarted, the crashing goes away and I'm able to play several games in a row without any issues, but considering the intermittent nature of the crash, I'm never quite sure when it will happen again.

I've attempted to reinstall the entire client, which unfortunately didn't fix the issue. I'm running the following hardware:
iMac 27-inch, Late 2012
Processor 3.4 GHz Intel Core i7
Memory 16 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GTX 680MX 2048 MB
Software OS X 10.9 (13A603)

Thanks for any input or advice.

Update, problem persists. I'm attaching some crash logs from console.


Deleted logs. I believe I tracked the issue down the Mumble's overlay. Disabling the overlay and uninstalling it stopped the crashes.
