Internationalization prevents uninstall of other addon and itself

Permalink
I tried to uninstall three addons but I get this error:

Fatal error: Cannot redeclare class MultilingualSection in /home/thison3/public_html/packages/multilingual/models/section.php on line 334


Line 334 is the closing "}"

I also can't unistall Internationalization and manually removing it make my site inaccessible.
