You would be incorrect on that - just because you aren't charging or discharging doesn't mean there isn't anything going on. A recent case at the Snowbirds saw a pack go up even though it had finished its discharge - was still hooked up to the charger though. Temperature fluctuations can make things happen too. I had a pack which had a slight bit of swelling and then one warm day I found that it had swelled further and popped the cause whilst not in use!
When we first started using lipos I read up on a few cases of lipo fires and one involved a bloke's plane going up in flames in his garage overnight. What they reckoned happened in that case was that the temperature had dropped overnight and that some condensation had caused the pack to short out.
