Crash after initial set-up on PowerPC: `KERN_PROTECTION_FAILURE at address: 0x00000000`

[barracuda156]

I got lastfm-desktop 2.1.39 built from source on PowerPC, it runs initially, I authorize it via the browser, go though initial set-up, but after clicking Finish it just crashes:

Program received signal EXC_BAD_ACCESS, Could not access memory.

Any idea what could be the cause for this?
