Accessing unistall webpage results in "unexpected error"

Hi,

I have installed fresh version of Drupal 8.0 in Polish lanagugage and installed some modules. Now when I am trying to access admin/modules/uninstall I get the following error "Wystąpił niespodziewany błąd. Proszę spróbować później." (Unexepected error had happened. Please try again later).

In the logs I see the following error:

Uncaught PHP Exception Drupal\\Core\\Database\\DatabaseExceptionWrapper: "SQLSTATE[42S02]: Base table or view not found: 1146 Table 'mage_kpse8.menu_link_content' doesn't exist: SELECT base_table.id AS id, base_table.id AS base_table_id\nFROM \n{menu_link_content} base_table\nGROUP BY base_table.id\nLIMIT 1 OFFSET 0; Array\n(\n)\n" at .../core/lib/Drupal/Core/Database/Connection.php line 676, referer: .../admin/modules

DB sql dump file included. No given table exists in a dump file.

Seems that simply installation of one of the modules could have been interupted (e.g. I may not exclude that I closed my webbrowser). I will give a try to another installation.
