[Ohrrpgce] SVN: teeemcee/10411 Fix a couple crashes or null slice ptr debug errors that occur if a ps.c

[Ralph Versteegen]

I'm assuming it's not meant to be possible to end up with no selection in
thingbrowser (eg, there doesn't seem to be any code to exit if you
right-click off a menu item, or anything like that), but it's written to
not crash in case that ends up being the case.
