Package: libtcl8.6
Version: 8.6.1-6
Severity: important
File: /usr/lib/x86_64-linux-gnu/libtcl8.6.so

While trying to rebuild python-seaborn package (in a clean chroot on
another box) I ran into the segfault causing build to fail.  Here
are the details from a gdb for that run.  Please let me know if I could
provide any additional information -- I will keep that session open.
