Default Play Store FC's

The Play Store app started FC'ing on my S4 about a month ago or so in various contexts. I've already tried wiping its data, uninstalling updates, then reinstalling. I'm able to reproduce the following FC, so maybe if I can solve this, I'll solve the whole problem:

While showing My Apps, if I quickly switch the device on and off, Play Store becomes unresponsive. I can press the home button and get to my home screen, but the UI otherwise is frozen for about 20 seconds until Play Store dies. At the beginning of the attached logcat, it says:
Code:
Select Code

broadcastEvent : com.android.vending system_app_crash
V/15:36:29.186 AlarmManager(24983)
trigger ELAPSED_REALTIME_WAKEUP or RTC_WAKEUP
Does that mean something to anyone?

The app dies 12 seconds later, at the end of the logcat, but I don't know if the stuff in the middle has any bearing after that app_crash entry. Apparently, that's the 12 seconds that my phone is locked up, though it seems longer. Any suggestions?
