Intermittent crashes of bitcoin-qt.exe (server=1) when using RPC commands. I can reproduce it fairly consistently, but I have been unable to find a set of steps to reproduce it 100% of the time. Included at the bottom of this issue is the crash.bat I used to recreate to problem fairly consistently.

I successfully reproduced the crash on bitcoin-qt.exe 0.5.0 rc5.

I was unable to reproduce the crash on bitcoin.exe 0.4.1, bitcoind.exe 0.4.1, bitcoind.exe 0.5.0 rc5.

Reproduced using bitcoin-qt.exe 0.5.0 rc5 on:

• Windows 7 x86
