[[plugin/recentchangesdiff]] causes rendering to segfault if a commit removes a lot of contents. I removed close to 400 files, total size of about 950Kb in a single commit and now `ikiwiki` segfaults on refresh and rebuild:
[...]
rendering recentchanges.mdwn
[1] 5541 segmentation fault ikiwiki --verbose --setup ikiwiki.setup --refresh
If I disable the plugin, the segfault does not happen, but I have to remove `wc/recentchanges/*` or else it will crash just as well.
This is reproducible, but I cannot provide the source code.

The tarball is at http://scratch.madduck.net/__tmp__recentchanges-segfault.tgz - unpack it in `/tmp` and `chdir()` to /tmp/cdt.taF18912, then run
ikiwiki --setup ikiwiki.setup
# segfaults
git checkout HEAD^
ikiwiki --setup ikiwiki.setup
# segfaults
rm -rf wc/recentchanges
ikiwiki --setup ikiwiki.setup
# works
