crash importing all pdfs - dev build

identical behaviour here on Win32 nightly build from May 8

Heh. If you look at line #0, this=0x0.

If you look at src/extension/internal/pdfinput/pdf-parser.cpp, line 1241:

void PdfParser::opRectangle(Object args[], int numArgs) {
  double x, y, w, h;

  x = args[0].getNum();
  y = args[1].getNum();
  w = args[2].getNum();
  h = args[3].getNum();
  state->moveTo(x, y); <-- HERE
  state->lineTo(x + w, y);
  state->lineTo(x + w, y + h);
  state->lineTo(x, y + h);
  state->closePath();
}

It looks like 'state' is null when state->moveTo(x,y) is called.

After running some debug stuff, I found that the best-looking culprits, PdfParser::saveState() and PdfParser::restoreState() are not the source of this. It must be elsewhere. The next-best clue would be that the "state" variable is being overwritten among the PdfParser data fields.

I think I'm done with this. Anyone who actually knows what's going on in PDF input care to look at this?

Miklos? You around?

just for fun, created an empty pdf file, tried to import it, got this crash message

C:\Python25\APP>inkcl.py
return code: -1073741819 (hex C0000005)
Error: Couldn't open 'nameToUnicode' file 'C:\target\share\poppler\nameToUnicode\a'
Error: May not be a PDF file (continuing anyway)
Error: PDF file is damaged - attempting to reconstruct xref table...
Error: Couldn't find trailer dictionary
Error: Couldn't read xref table

the implication seems to be that the crash occurred before the file was opened

traceback follows :

sorry, that was not very interesting, next I created a valid .pdf file consisting of the word "Hello", attached here.
backtrace is below :
the only thing that seems to be in common in these three cases is the line

running win32 version of Inkscape 0.46, the pdf file loads properly, but I get the following DOS exit message after a normal exit:

(inkscape.exe:2916): Gtk-CRITICAL **: gtk_file_system_win32_get_info: assertion `g_path_is_absolute (filename)' failed
Error: Couldn't open 'nameToUnicode' file 'C:\target\share\poppler\nameToUnicode\
'

the nameToUnicode reference is common to both cases, with or without crash

I have the exact same problem, WinXP2SP2, inkscape dev build June 5th. I tried using inkscapec.exe (thanks JH!) to see what happened, the result is this....

Open a cmd window and run inkscapec.exe.
Open any pdf document and the preview appears - as the preview window opens, I get an error in the console -

C:\Program Files\Inkscape0.46>inkscapec.exe
Error: Couldn't open 'nameToUnicode' file 'C:\target\share\poppler\nameToUnicode
\a'

(On multiple attempts the path was the same but the 'filename' (a in this case) varied.)

When you accept the pdf preview, inkscape crashes with no other notification to the console.

Is there a possibility that the C:\target\ reference is wrong? I know target is often used as a variable for compiling but C:\target\ doesn't exist on my system so if that is where it is looking then it won't find anything.

I don't know if this helps or not but if there is anything I can try then just let me know,

Thanks,

Tony

Looks like a Poppler bug:
http://lists.freedesktop.org/archives/poppler/2008-April/003661.html

Upgrading to latest Poppler plus applying the patch from Bug #237574 solves the crashes for me.

Any chance of anyone releasing a new set of devlibs to take account of this change? I tried and tried to compile poppler on windows and gave up in the end.

Pdf import works perfectly for me now . Inkscape SVN 18906/ devlibs SVN 5

Many thanks,

Tony

running win32 build Inkscape0806131634.7z.
.pdf import works fine and also Adobe Illustrator 9.0 import works fine,

Many thanks,
Alvin

Can you please give a link to the develibs you're using? I used this one:

http://inkscape.modevia.com/win32libs/devlibs-2.12-svn-0805081735.7z

and still getting a crash on pdf import on XP:

That's the right devlibs package. But you need to do svn update on the devlibs directory before you use it, as it's a little out of date. (You will also need to rebuild Inkscape from scratch, due to some binary incompatibilities.)
