Comment (by daira):

 I patched the magic folder code to print out log messages, and forced a
 build of [https://github.com/daira/tahoe-lafs/commits/2834.enable-magic-
 folder-logging.0 that branch].

 The [https://tahoe-lafs.org/buildbot-tahoe-
 lafs/builders/Debian%20Jessie/builds/11/steps/tox/logs/stdio Jessie] and
 [https://tahoe-lafs.org/buildbot-tahoe-
 lafs/builders/Ubuntu%20xenial%2016.04/builds/6/steps/tox/logs/stdio
 Xenial] builders, which both succeed, have the same pattern of events:
 "`local_dir/empty_tr\xc3\xaae` moved_to, is_dir" once, as expected.

 The [https://tahoe-lafs.org/buildbot-tahoe-
 lafs/builders/Centos%207/builds/2/steps/tox/logs/stdio Centos], [https
 ://tahoe-lafs.org/buildbot-tahoe-
 lafs/builders/Fedora%2024/builds/4/steps/tox/logs/stdio Fedora], and
 [https://tahoe-lafs.org/buildbot-tahoe-
 lafs/builders/Markus%20slackware64%20stable/builds/283/steps/tox/logs/stdio
 Slackware] builders, which fail, have a different pattern:
 "`local_dir/empty_tree` moved_to, is_dir" '''twice''', then
 "`local_dir/empty_tree` delete_self".

 It's unclear whether the filename being Unicode on the succeeding systems
 and ASCII on the failing systems is causative or a coincidence, given that
 the pattern of events is also different.
