Hi,
In some modes (tex-mode), `find-tag-default' can misbehave and
error.
It is annoying if you cannot `describe-function' or
`describe-variable' in such a mode, so I propose the following
patch. (`function-called-at-point' and `variable-at-point'
already use condition-cases. But an alternative would be to wrap
`find-tag-default' itself in a condition-case.)
