From experience I can say that a 'preventable random glitch' really does exist - I have personally created - and fixed - many of them. I get concerned only when I see many reports of fixing them long after the product has been released.
In physics an event is random or it is not random. There is no state between those two possibilities. So, as I explained a 'preventable random system glitch' is a contradictio in terminis. I think we are too much accustomed to 'random' processes (in software) that are artificially created and actually semi-random. It is not possible to create a true random process with software. True random signal generators are always using a physical process, for example thermal activity from ions, or particles that are emitted from a radioactive material.
Going back to the subject, a matter of more concern is the reliability of the new firmware itself, because in the past it has often happened that within one or two days Pentax published yet another update to compensate for new errors. So that is a valid reason to delay installing the new firmware.
