[gtkmm] resource file styles and x server resource leak

[pks timing com]

When running the following program, built with gtkmm 1.2, with the
resource file that follows the code, I observe my x server growing
4K every ten to fifteen seconds. When I terminate the program the x
server's memory usage returns to what it was before the program was
executed.

For what it is worth, I'm running FreeBSD 4.5 and leak rate
described above applies to an amd-k6 265.27-MHz with 64MB of
ram, running an svga x server. My p4 with a much beefier video
card also leaks when this program is run, at longer intervals
and much larger increments (236K at a time).

Any and all input on this matter will be appreciated.

Thank you,

Patrick Schweiger
