When you bind an extension to an application; the text in the context menu doesn't change; it still shows 'Open with other application'. The strange thing is that when you click 'Open with other application' [for the second time] it will open the application to which the extension was just bound. It seems to refresh [show the selected application in the context menu before the 'Open with other application' entry] after reloaded [CRTL+R] the view; but it might be the deselecting<>selecting as well which does it

Reproducible: Always

Steps to Reproduce:
1. Create an unknown extension with unrecognizable content; for example `cat /dev/urandom > /tmp/test.extension` [just ctrl+c it quickly]
2. Point Thunar to the directory /tmp
3. Right-click on the file and select 'Open with other application' and select an application [I selected gvim]
4. Right-click the file again.
Actual Results:  
The context menu is the same, it doesn't show gvim.
5. Click on 'Open with other application'. Gvim will be opened with the selected file open; instead of the expected application selector

Expected Results:  
After having selected an application; the context menu should reflect this choice immediately; instead of waiting for the context menu to be regenerated due to reloading the view
