Ali sent this privately to me as a potential security issue.
I am not a security expert and I certainly don't consider this
a big enough problem to discuss privately...

The potential issue is exposing path names of Xapian installs.

I figure installation paths of open source software
(particularly with FHS / LSB systems) is well-standardized to
the point that it's pointless to obscure or obfuscate anyways.

*shrug*

Subject: [PATCH] searchview: don't be too verbose about bad queries

This is to omit the message "something terrible happened at .."
from the http view when searching, since it contains absolute system paths.
This is debug information and shouldn't be displayed to the user.
