Hello,

I'm not using tel2uri(). I tested it again and I can't reproduced it with
the last commit in 4.1 branch. With version 4.1.3 it reproduces always. The
problem seems to be present after more than one mysql query thus I thought
it could be related with that commit. I try it
at 642428cf8be1c7355f91b14276e888ec505cd69a and it also reproduces so it
seems that it is solve by 94ebfb5d5973ed59de84ca0e0c87052b4c80f9de.

The complete log for version 4.1.3 is here:
