Bug #84149
Updated by Oliver Hader about 6 years ago
On using associative array in LocalizationUtility which is e.g. used by Fluid's TranslateViewHelper, the error @Cannot unpack array with string keys@ is thrown. The reason is that @sprintf($value, ...$arguments)@ cannot be used with @$arguments@ being an associative array.
The behavior can be reproduced in TYPO3 v9.2-dev when installing an extension in the extension manager that has e.g. insufficient version dependencies.
