Bug#542399: tuareg-mode: caml-types-explore fails with "Wrong type argument: stringp, 116"

[Lionel Elie Mamane <lionel@mamane.lu>]

Package: tuareg-mode
Version: 1:1.45.6-2
Severity: normal

C-c C-t works and shows the type of the expression under the cursor,
but <C-down-mouse-2> puts in the mini-buffer/message area "Wrong type argument:
stringp, 116". Looking in buffer "*Messages*" shows:

caml-types-pos-inside: Wrong type argument: stringp, 116
