Description David 2008-07-28 13:55:01 UTC

Steps to reproduce:
1. Download this PDF http://www.csb.gc.ca/s40rates/2007_11_CS47.pdf
2. Open it in evince ( or using evince-thumbnail )
3. watch your memory usage carefully.

According to the responder on Gnome, the bug is in poppler. There is a file that shows memory usage of the application during the problematic time.

I am not sure how you guys decide priority, so I put it at high. It prevents me from using the software, so according to me it should be blocker.

Comment 2 Albert Astals Cid 2008-07-28 14:35:12 UTC

Does not happen with the splash backend, reassigning to to cairo backend

Comment 3 Carlos Garcia Campos 2008-07-29 00:42:15 UTC

what poppler version are you using?

Comment 4 Martin Wolf 2008-07-29 02:40:25 UTC

Version 0.6.4 and
Version 0.8.4 and
Latest from git, about 15 hours ago.

Image-heavy Microsoft pdf (testcase)

I think the attached pdf file is a good testcase for this bug: in my box, evince takes up to ~840MB of ram memory to open it.

Another test case

I recommend testing the bug with 512 mb of memory or less.

Comment 7 Atanas Atanasov 2010-01-03 04:49:40 UTC

I can confirm the bug. I placed a similar report in https://bugs.launchpad.net/bugs/491531.

Two minimal similar PDF files, one triggers the bug and the other does not

Here is a test case (see attached file isolated-test-case.zip) that properly isolates the bug. The following 2 files were made using Inkscape (ubuntu 9.10). The only difference between them is that the image that they contain was:
 * pasted from another inkscape document (file bug.pdf, 4kb)
 * dropped from nautilus (nobug.pdf, 2.4kb).

Note the different file sizes.
I hope that these files will allow to easily track down what triggers this bug.

This bug might cause a loss of data, because a low resource 5-years-old machine (512Mb RAM) becomes totally unresponsive and the only way to stop evince or evince-thumbnailer is to hard reset the computer.

Regards,
Ric.

Fixed here with poppler 0.14.2 (ubuntu 10.10 beta)
