I have committed the patch by Ulf Erikson that adds native PDF export
(based on PS export code). It has many limitations but at least it's
better than what we have now, because it does not require Ghostscript
and, most importantly, handles transparency. Complex illustrations,
such as this one:
http://www.inkscape.org/screenshots/gallery/inkscape-0.41-CVS-linux-davin...
are shown quite faithfully by Adobe Acrobat after saving as PDF
(though much slower than in Inkscape... and I thought our renderer is
the slowest, heh).
Current limitations include: no text (check "Convert text to path"),
no gradient on stroke, no clipping/masking/patterns, no eccentric
elliptic gradients, no bitmaps.
I know we're probably going to have at least one SoC student working
on PDF export, and I think it will make a perfect sense for that
student to work on this existing code to improve it. However, even if
the student will choose some other approach (e.g. using Cairo), it
will be easy to replace this code. For now, however, it's the best we
have, and I want this to be in 0.44.

My gdb skills are rather rusty but if more info is needed I can try to
provide it.

Please file a bug with sample file, steps, all your libs etc.
From this:
*** glibc detected *** /home/tavmjong/sandbox/bin/inkscape:
munmap_chunk(): invalid pointer: 0x0b9fa47c ***
it looks very much like compiler version incompatibility, though I'm
not sure why it's triggered by PDF export. Try to recompile all the
C++ libs with the current compiler.

Line 315 of pdf-mini.h reads "delete resources;", but since 'resources'
was allocated with "new PdfXref[11]();" it must be "delete[]
resources;". Such a fault is likely to cause memory corruption and/or a
crash. Can someone able to reproduce this crash please try the fix and
report back?

That fixed the crash for me! Thanks!

I reproduced a problem (but not actual crash) on OS X, applied this
fix, and verified that it corrected things.

I just tried on win32 and am getting the error:
'ps2pdf.bat' is not recognized as an internal or external command,
operable program or batch file.

That's the old one. I guess I need to delete it. (Or you're not
running the latest.) Here on Linux, the new internal extension somehow
shadowed the old one, but maybe it's only here.
It would be best if Ted could have a look at this...

Thanks for pointing that out about it being the old one. I feel like an
idiot... I normally just overwrite my builds every day. I deleted the
dir and extracted it "fresh" and everything is golden. Thank you!
