Got several problems with Chrome as well. On an iPhone 5 with Nitrous installed - and on one without.
Sadly, some random resprings are happening here as well. Crashlog showing low memory warnings before that. It was a perfect clean install and I only got some popular tweaks running with nothin' messed up.
And from what I observe ppl with problems almost always have Auxo & Zephyr installed.
I don't have any tweaks like that. I have MobileSubtrate and Substrate Safe Mode and iFile, that's it.
