Hi!
I am running Bitcoin Core version v0.12.0.0-g188ca9c (64-bit) on Ubuntu 14.04 and I have the following problem:
If I delete / remove the wallet.dat file (with my keys) the client runs stable for hours or days.
But if I copy my wallet.dat file and start bitcoin-qt (even with -rescan) it just rescans successfully but then crashes after a couple of minutes with errors like:

I also noticed something strange:
The freshly created wallet.dat (if no wallet.dat is found) has 81,9kb size whereas my wallet.dat only is 53,2kb?
Can somebody help please?
Thanks!
