fix major memleak

[Andreas Mohr <andi@rhlx01.fht-esslingen.de>]

Hi all,

this fixes a memleak in find_child_from_point().
It wasn't freeing the child window list in a lot of return cases.

This should resolve bug #590.
And I should be happy :-)

AbiWord, which was mentioned by the bug reporter in a mail,
doesn't eat mem on the toolbars any more...
