Plugin Search for empty string can hide all Plugins

[hakre]

I'm seeing something weird on trunk, I have checked against 3.0.5, it does not have that problem:

Searching for a plugin that does not exists (e.g. "new version") will create an empty listing. Searching again with an empty search will remove the search and keep the empty listing.

I would have expected the behavior that the list of plugins is visible again.

Steps to reproduce:

1. Go to the "Plugins" page (Plugins -> Plugins)
2. Enter "new version" into the search box and press the "Search Plugins" button right next to it.
3. The page is requested again now displaying an empty plugins list.
4. Delete "new version" from that search box (empty the search box) and press the "Search Plugins" button right next to it.
5. The page is requested again now displaying an empty plugins list.

It should not display an empty plugins list in (5.).

This seems to be corrected in the current trunk (3.5-alpha-21751).

Fixed in [18991].
