Bugfixes all day.

The most amusing bug, which I just stumbled over randomly on my own, after someone on IRC yesterday was possibly encountering the same issue, made git annex webapp go into an infinite memory-consuming loop on startup if the repository it had been using was no longer a valid git repository.

Then there was the place where HOME got unset, with also sometimes amusing results.

Also fixed several build problems, including a threaded runtime hang in the test suite. Hopefully the next release will build on all Debian architectures again.

I'll be cutting that release tomorrow. I also updated the linux prebuilt tarballs today.

Hmm, not entirely bugfixes after all. Had time (and power) to work on the repository configuration form too, and added a check box to it that can be unchecked to disable syncing with a repository. Also, made that form be displayed after the webapp creates a new repository.
