I got my command for
Ctrl+C - c - t (i.e. invoke org-capture) slightly wrong (i.e. missed a key or something when trying to type it). I know I got it wrong because it didn't work but instead changed something in one of my open buffers slightly (sorry, I can't remember what, and I don't know what key I mistyped). Now, if I try to use Ctrl+C-c-t again, it's giving me the following debug error:
Debugger entered--Lisp error: (error "Selection owner couldn't convert" UTF8_STRING) x-get-selection-internal(CLIPBOARD UTF8_STRING nil nil) #f(compiled-function (selection-symbol target-type &optional time-stamp terminal) #<bytecode 0x1fe12375f05f>)(CLIPBOARD UTF8_STRING) apply(#f(compiled-function (selection-symbol target-type &optional time-stamp terminal) #<bytecode 0x1fe12375f05f>) (CLIPBOARD UTF8_STRING)) gui-backend-get-selection(CLIPBOARD UTF8_STRING) gui-get-selection(CLIPBOARD UTF8_STRING) gui--selection-value-internal(CLIPBOARD) gui-selection-value() current-kill(0) org-capture-fill-template() org-capture(nil) funcall-interactively(org-capture nil) call-interactively(org-capture nil nil) command-execute(org-capture)
This is entirely opaque to me -- any idea what it might be and how to fix it?
