Comment (by mig5): The good and bad news is that I can't seem to reproduce this now! Still a Fedora 26 AppVM in QubesOS - the only thing that's different is newer Tor, so perhaps this bug was somehow fixed in 0.3.1.10. {{{ Mar 21 07:37:13.832 [notice] Tor 0.3.1.10 (git-e3966d47c7252409) running on Linux with Libevent 2.0.22-stable, OpenSSL 1.1.0g-fips, Zlib 1.2.11, Liblzma N/A, and Libzstd N/A.
