app_server crash, segment violation

[humdinger]

This is hrev43696.

Just crashed app_server into gdb. I might have closed or reset the type-ahead-filter of a Tracker window showing web+ bookmarks. Syslog says (dunno where it ends, after stacktrace I quit gdb, entered KDL and "reboot"ed):

Still reproducible?

Haven't seen that one, I think. Must've healed over the last 10 years...
