I saw this as well, but if you set it sit for a moment, you'll notice that it's hitting a critical section timeout.
Attaching that info, along with the output of winedbg 'bt all' would be helpful.
Mmm looking back a chat log I sent someone I do actually recall getting this at one point. Here is the output at the time (I haven't seen it since though).
err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr 0x6814c1de wine client error:3b: write: Bad file descriptor
