Not found am-newsblog.xul

Enabling FiltaQuilla causes an error when I open the Account settings of Feed. It says chrome://messenger/content/am-newsblog.xul cannot be found. It also makes Feed Accounts undeletable.

Thanks - I was able to reproduce the problem, no idea yet what exactly is happening.

Error console says:

Error accessing panel from extension 'mesquilla-extension-inherit-pane': [Exception... "Component returned failure code: 0x80570016 (NS_ERROR_XPC_GS_RETURNED_FAILURE) [nsIJSCID.getService]" nsresult: "0x80570016 (NS_ERROR_XPC_GS_RETURNED_FAILURE)" location: "JS frame :: chrome://messenger/content/AccountManager.js :: at_build :: line 1568" data: no]

So I started the debugger and set a breakpoint and examined it. I attach the following image.
