Bug#914652: nautilus: takes many seconds to start; becomes irresponsive on search

[Leandro Doctors]

Package: nautilus
Version: 3.30.3-1
Severity: important

Dear Maintainer,

   * What led up to the situation?

        Starting the program. Or performing a search once the program has
loaded.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

        I tried to execute the program. I tried to perform a search using the
address bar.

   * What was the outcome of this action?

        The program takes many seconds to load (5-10). Sometimes, it does not
load at all. When trying to search, sometimes it becomes irresponsive.

   * What outcome did you expect instead?

        The program should start instantly. The search results should start
appearing after a short delay (1-2 seconds).
