One thing that would be cool with the runtime loading of VTE is if it 
could gracefully handle missing symbols in libvte.  I don't know if this 
is possible with GModule/dlopen, but if it is, it would be great to 
implement this.

For example, I'm testing Geany with GTK+ 2.16 and when it goes to load 
the VTE, it loads the system one that was compiled against GTK+ 2.24 and 
Geany crashes with the output:

/opt/geany-2.16/bin/geany: symbol lookup error: /usr/lib/libvte.so.9: 
undefined symbol: gtk_widget_set_can_focus

To make Geany run, you have to use the `-t` option to disable the 
terminal or install a libvte compiled against the same GTK+ version as 
Geany and specify its path with the `--vte-lib` option.  It would be 
nice to be able to handle such a case of missing symbols and just 
disable the VTE automatically, even though it might not be experienced 
too frequently on a typical system.
