Package: libxi6
Version: 2:1.7.8-1
Severity: important
Dear Maintainer,
after upgrading libxi6 from 2:1.7.6-1 to 2:1.7.8-1 the ksmserver crashes when
closing lid and desktop should lock. Downgrade to the older version helps and
it happens every time. See the backtrace. When ksmserver crashes, the whole
session is terminated, so it is quite unplesant crash.
Thank you.
