milestone: NEEDS_TRIAGE => SSSD 1.9.4

We could never reliably reproduce the problem nor could the reporter for the last couple of days. We'll still be tracking the bug as we gave the reporter an instrumented build and a gdb script to help us see what's wrong.

But this is not blocking the 1.9.4 release anymore. Bumping to 1.9.5

milestone: SSSD 1.9.4 => SSSD 1.9.5

The corresponding Fedora bug was closed as worksforme. We patched the host handler to not crash if the data was uninitialized (as do the other handlers already).
