That's why I'm hesitant to add themes. My phone has been a little flaky too. My issues aren't as exotic as yours though. Just an occasional spontaneous app closing or reboot.I've had more minor issues with this jailbreak than any other in the past, but I don't blame the jailbreak itself. It's that a lot of the apps and tweaks aren't fully compatible with the firmware or each other. It's nothing serious; just random resprings and occasional crashing apps. The strangest one is when my dock starts flashing in a rapid strobe-like pattern about 3x per second. It only happens when I'm on a phone call (I use Bluetooth so I can see the screen, if you're wondering) and it goes away when I tap the screen. I'm not using WinterBoard or any dock tweaks. I've had the phone lock up a couple times as well, but a hard reset worked.
