Crash with "hg incoming"

[Lorenz Minder]

Hi,

I get the following crash when doing "hg incoming" on a mirror of the
Linux kernel repo. It might be related to issue 528, but I don't think I
use the keyword extension. (That is, I have no idea what the "keyword
extension is.)

As witnessed in the transcript, the repo passes "hg verify", and the
crash appears to be reproduceable.

Let me know if I should provide more info, or if this is fixed in a
newer version.

Best,
--Lorenz
