Yag 4.1.2 Autoload error

[itawde]

Using Yag 4.1.2 on TYPO3 7.6.11. I get the following error in the TYPO3 BackEnd:
#1289386765: Could not analyse class: "Tx_Yag_ViewHelpers_Link_GalleryViewHelper" maybe not loaded or no autoloader? PHP Warning: Declaration of Tx_PtExtlist_ViewHelpers_Link_ActionViewHelper::render($action = NULL, array $arguments = Array, $controller = NULL, $extensionName = NULL, $pluginName = NULL, $pageUid = NULL, $pageType = 0, $noCache = false, $noCacheHash = false, $section = '', $format = '', $linkAccessRestrictedPages = false, array $additionalParams = Array, $absolute = false, $addQueryString = false, array $argumentsToBeExcludedFromQueryString = Array) should be compatible with TYPO3\CMS\Fluid\ViewHelpers\Link\ActionViewHelper::render($action = NULL, array $arguments = Array, $controller = NULL, $extensionName = NULL, $pluginName = NULL, $pageUid = NULL, $pageType = 0, $noCache = false, $noCacheHash = false, $section = '', $format = '', $linkAccessRestrictedPages = false, array $additionalParams = Array, $absolute = false, $addQueryString = false, array $argumentsToBeExcludedFromQueryString = Array, $addQueryStringMethod = NULL) in /<...>/typo3conf/ext/pt_extlist/Classes/ViewHelpers/Link/ActionViewHelper.php line 0

Any hint is appreciated!

i guess you're using php7?

the matching of interfaces and implementations is tighter.
actually this is a "class" of bugs, that has to be fixed in pt_extlist -> punktDe/pt_extlist#19

Had quite a similar bunch of warnings and errors on my installation while loading images into the BE!
Server: Ubuntu 16.04, Linux 4.4.0
PHP: 7.0.8
Typo3: 7.6.11 and 7.6.12
DB: 5.7.12
YAG: 4.1.2
pt_extbase: 2.2.0
pt_extlist: 2.3.0

Here are the first warning and the error at the end:
Core: Error handler (BE): PHP Warning: Declaration of Tx_PtExtlist_Domain_Model_Filter_FilterFactory::injectObjectManager(TYPO3\CMS\Extbase\Object\ObjectManagerInterface $objectManager) should be compatible with Tx_PtExtlist_Domain_AbstractComponentFactory::injectObjectManager(TYPO3\CMS\Extbase\Object\ObjectManager $objectManager) in /var/www/html/photores/typo3conf/ext/pt_extlist/Classes/Domain/Model/Filter/FilterFactory.php line 38

... a few more warnings then ...

Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1247602160: Incorrect string value: '\x8F\xAE\xF6?G-...' for column 'exif' at row 1 | TYPO3\CMS\Extbase\Persistence\Generic\Storage\Exception\SqlErrorException thrown in file /var/www/html/typo3_src-7.6.12/typo3/sysext/extbase/Classes/Persistence/Generic/Storage/Typo3DbBackend.php in line 879.

Any idea how to fix this ? Hints are very welcome, thanks.
