bitcoin-qt.exe crash with disablewallet #4013

When I try to run bitcoin-qt it hard crashes when I have "disablewallet" in bitcoin.conf.

When I replace it with "disablewallet=true", it doesn't crash, but I still see my wallet and transactions.

When I replace it with "disablewallet=1", it works as expected.

https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File implies that this should be possible, but doesn't give any examples. I believe that disablewallet=1 is correct, but I only discovered it through experimentation.

I've managed to replicate this, the config file parser seems to require each key to have a value (if it doesn't Bitcoin crashes) and it doesn't recognise true or any string as being true.

"disablewallet=n" where n is an integer and not 0 disables the wallet.

It indeed doesn't recognize 'true'. Values of such options must be 0 or 1.

Sounds like a bug in the config file parser that it crashes on bare disablewallet.
