Re: [API 2.4] font in entry

[Yann Leydier <yann leydier info>]

Here is some information to add to the subject: connecting my function 
to signal size-request or size-allocate works when the signal is called 
for the second time.

This solution is unsatisfying as the signal is emitted quite often and 
it isn't easy to disconnect the signal only when not needed anymore.
