Comment (by davidsarah):

 Replying to [comment:1 davidsarah]:
 > This error [...] happens when:
 >  * the {{{--version}}} or {{{--version-and-path}}} option to
 {{{bin/tahoe}}} is used, and
 >  * the version of a package obtained either from import or from
 pkg_resources, is not parseable at all by
 [source:src/allmydata/util/verlib.py]. (A non-normalized but parseable
 version is fine.)

 Oops, {{{cross_check_pkg_resources_versus_import}}} is also called by
 [source:src/allmydata/__init__.py at 4994#L378 get_package_versions_string],
 which is used [source:src/allmydata/node.py at 4852#L4775 when constructing a
 storage client or introducer node]. This will prevent running nodes
 whenever the second condition above holds.

 This situation is not happening on any of the buildbots, so it can't be
 very common. However I think it still requires a 1.8.3 :-(
