[O] Capture mode fails until "reload org uncompiled" is used

[Felix]

When I fire up emacs and use C-c c t to enter a task (see .emacs below), I get
the message "Capture template `t': org-called-interactively-p" and nothing
happens. However, if I use the menu option "Org->Refresh/Reload->Reload Org
Uncompiled", then C-c c t works correctly every time. I have provided a
backtrace below (without "reload org uncompiled", since that fixes the problem).

Any suggestions to fix this so that I don't have to "reload org uncompiled"
every time I start emacs? Thanks.
