Segfault when clicking place where Payment Request QR code should be, after entering Message that was too long. #4140

Procedure:

1. Open Bitcoin Core client
2. Go to the Receive tab
3. Create a new payment request with a message that is too long (in my example: "This is a payment request. It gives us a QR code, a link, and an address which we can pass onto the person we are requesting payment from." - 138 characters
4. Click on the placeholder for the QR code (which is rightly empty).

Expected behaviour: Do nothing.

Actual behaviour: Segmentation fault (core dumped)

OS: Linux Mint 13 64-bit Bitcoin Core version: 0.9.1, static binary from bitcoin.org website.

edit: Things I'm doing differently but are probably not related: My ~/.bitcoin folder is symlinked from a different hard drive. I am using BtrFS on an SSD as main partition, but said ~/.bitcoin folder is on an ext4 spindle drive.

Seems there is an on click action, which doesn't work, when there is no QR Code or such a thing.

Good catch
