Are you not able to remove smart connect? I know that it comes pre installed on Xperia devices. If you can remove it that would be best. It is probably blocking the apk from installing. See if it lets you uninstall updates.
I bought the phone and accesories 2 weeks ago. I didnt need to check other applications outside play store, yet. Sorry but ur screenshots arent viewing again. there are triangels instead of pictures. 
Okay. Are you on your phone? I get the same issue with the pictures on my phone using chrome as my browser. Does your Smart Connect give you the ability to uninstall updates?
I m on laptop. nd not viewing the pics. There is just smart connect updates uninstalling. Nd There is no uninstall option for all smart connect. Just disable it.
Try the updates uninstall and see what version it puts you on.
5.4.8 the version. on factory based. without updates.
Don't allow it to update and see if that version will work. I gave my findings to a chat support agent earlier. I don't know if they are able to send you an older version of the app. If that works, turn off updates for the app.
It's from July 2012! Are you kidding!?

Screenshot show that your are running kitkat (4.4.2) on a Xperia Z ultra Google Edition (without any Sony pre-installed software) and the thread is about application crashes just after after Official Sony Androïd 4.3 update.
Not sure if your suggestions fully apply to the context.
For example did you have also the application crash when trying to off text to speech function ?
