SIGSEGV in g_action_map_lookup_action() (same as bug 746829)

I use file-roller on Ubuntu 18.04.2 LTS (amd64). The version provided there is 3.28.0-1ubuntu1. Ubuntu recommends filing this bug report upstream.

I initially reported this as Ubuntu bug #1817464 - a duplicate of Ubuntu bug #1725017.

This was previously filed against your old bug tracker (whose bug reports apparently didn't get imported here - yet?) as Bugzilla bug #746829.

Ubuntu's crash handler receives about ten reports per days on this for the past few years.
