Memory leak on --export-pdf, --shell mode

[yko]

Looks like Inkscape doesn't release ram after pdf export in --shell mode.
Best way to reproduce:

wget http://upload.wikimedia.org/wikipedia/en/c/ce/SVG-logo.svg
for i in `seq 1 10000`; do echo "--export-pdf=test.pdf SVG-logo.svg"; done | inkscape --shell

This will eat available ram not too fast, but speed of ram consumption depends on SVG file size.

Inkscape 0.47 r22583 (Apr 4 2010)
Ubuntu 10.04.1 LTS

Just FYI

Looks like SVG-logo.svg doesn't contain any text element.
I also tested with empty SVG file, just like

<?xml version="1.0" standalone="no"?> <svg xmlns="http://www.w3.org/2000/svg" version="1.1"> </svg>

And got the same result. But i'm not familar with Inkscape internals, so this just for your information.

Reproduced with Inkscape 0.48+devel r10059 on OS X 10.5.8 i386
(for 2000 loops, memory usage grows about 20 MB, using the SVG-logo.svg)

Maybe related, I run PNG exports without --shell, with various SVG input, about 1 per second, and after couple of minutes there is inkscape process growing memory and CPU usage, then it terminates, difficult to tell with what outcome.

Inkscape may not release RAM for any shell mode command. I'm using it for SVG-to-PNG conversion (command passed to shell mode is roughly `source.svg --export-height=20 --export-png=dest.png`). I'm doing this for potentially tens of thousands of not-very-complicated files and Inkscape's memory usage can get into multiple gigabytes.
