Problem with Google streetview and firefox

[Mike Clarke]

Google streetview worked fine with Firefox before my recent upgrade of ports but I now have a problem. On starting 
streetview I see the image but cannot pan, zoom or exit from streetview, in fact Google maps becomes totally unresponsive 
and the image window eventually goes black.

-rwxr-xr-x  1 root  wheel  3897288 29 Oct 19:24 /usr/local/lib/qt4/libQtCore.so.4.8.5*

I've pasted the first part of a log file below. The "Locale not supported" message appears as streetview starts and the 
"libQtCore.so.4: cannot open shared object file" message appears as soon as I move the mouse in the streetview window. 
The "Event: assertion failed" messages continue until I move the mouse out of the streetview area of the window.

I see this problem with both firefox-esr-24.1.0_1,1 and firefox-25.0_1,1 but streetview works fine with midori-0.5.5_1.

I have checked with Firefox in safe mode with all plugins disabled and still see the same problem.

(npviewer.bin:2542): Gtk-WARNING **: libQtCore.so.4: cannot open shared object file: No such file or directory
The program 'npviewer.bin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 222 error_code 8 request_code 142 minor_code 3)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
