Moving to cairo backend, i can't reproduce the crash using pdftotext or qt4 test tools but can reproduce it using the glib demo (crashes extracting text from page 2)

I can still reproduce this with Karmic, will send it upstream, thanks.

This fixes it, but may be a hack

I threw this patch together very quickly after looking at the problem. It fixes the problem but I have not looked into this in-depth yet and it may be a hack.

I have been looking at this bug. I wrote a little about it here - http://www.vartmp.com/blog/subjects/poppler/20091219.html

The segmentation fault happens when the TextWord constructor is called. Specifically, when the constructor is called from the beginWord method. The reason the segmentation fault happens is because the curFont object has not been created prior to this, despite it being one of the parameters sent to the TextWord constructor.

On the basis of seeing this, I did a four-line hack in the beginWord method that checks for the existence of curFont, and if it does not exist, creates it and then calls "fonts->append(curFont)". After this, evince stopped crashing on the pages of the PDFs that it has been crashing (segfaulting) on.

However, I have not really looked into this indepth, what I did was just a hack. I am looking through the code of evince and poppler right now, and recreating the segfaults. It is possible that there is a better way to solve this, perhaps creating the curFont object in a different method, or who knows. If I come up with something better I'll give you an update. Or if one of you see something better that's good too.

Thank you very much for the patch, what poppler version are you using? I fixed this problem in poppler git recently, I didn't realize it was reported here too so I didn't close this bug, sorry. The commit that fixes this is:


Feel free to reopen if it still crahes with current git master. Thanks.

As stated in the gnome-bugs thread that is linked to in the remote bug watch panel, a fix was committed to the code base earlier this month. I downloaded the current poppler code via git and ran evince against that library for the problem files mentioned. With the new poppler library, there is no more segfault, the bug has been successfully fixed upstream.

The fix is out of the source tree and into a release - poppler-0.12.3. It is referred to in that release by its gnome bug # that is being watched here, gnome-bugs #603934.
