nautilus becomes unresponsive during find-as-you-type search with less than 3 letters

[Tomislav]

Observed behaviour: Start nautilus (shows my home dir), start typing e.g. "16", nautilus starts searching, showing some partial search results, but becomes completely unresponsive for about 15-20 seconds. After that it shows search results and responds to interaction. When deleting the search criterion, it freezes again for a similar amount of time.

Expected behaviour: Nautilus should respond to commands (e.g. double-clicking on a shown file, open a new Nautilus window...) while the search is running. When clearing the search field, it should refresh the view nearly instantaneously.

Reproducibility: every time, countless times

Workaround: wait it out or use at least 3 letters in the search, which seems not to trigger the above behaviour.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version.
