   This is the first time I heard of this, may I ask if the converse
   is true, ie. GPL -> LGPL?

No, that would do allow people to make the GPL weaker, subverting the
whole point of the GPL.  Here is the relevant section from the Lesser
GPL version 2:

|   3. You may opt to apply the terms of the ordinary GNU General Public
| License instead of this License to a given copy of the Library.  To do
| this, you must alter all the notices that refer to this License, so
| that they refer to the ordinary GNU General Public License, version 2,
| instead of to this License.  (If a newer version than version 2 of the
| ordinary GNU General Public License has appeared, then you can specify
| that version instead if you wish.)  Do not make any other change in
| these notices.
