TYPO3 Core

There seems to be a problem with the new page wizard:

If I create a new Page through the new page wizard, the entry in the table cache_hash with ident "TS TEMPLATE" seems to loose some constants...

It seems, that creating a new page through the wizard delets the cache of all sister-sites on the same level, as well as updates the entry ident="TS TEMPLATE" in the table cache_hash. This results in not rendering content elements on the final webpage upon deleting the whole FE-Cache by hand.

an example entry of the mentioned ident="TS TEMPLATE" record in cache_hash

ok:
"tx_srlanguagemenu_pi1->main";s:12:"templateFile";s:70:"typo3conf/ext/sr_language_menu/pi1/tx_srlanguagemenu_pi1_template.tmpl"

not ok (wrong):
"tx_srlanguagemenu_pi1->main";s:12:"templateFile";s:49:"{$plugin.tx_srlanguagemenu_pi1.file.templateFile}"

instead of filling the value correctly (value assigned in the constants-field of the setup), it inserts the string used in the setup field of the template.

I tried to reproduce this behaviour on different servers with 4.1.6 and 4.1.7. It only happens when creating a new page with the wizard, and it doesn't when I select "create new page inside" or "create new page after".
