Papers crash with a segment fault after opening a PDF file

[Marcos Alano]

I got a segfault when I try to open a PDF file. Here is the error:
➜ papers 5_open_source_collaboration_tools.pdf

(papers:357562): Gtk-WARNING **: 12:06:50.532: No IM module matching GTK_IM_MODULE=cedilla found
[1] 357562 segmentation fault (core dumped) papers 5_open_source_collaboration_tools.pdf

I attached the PDF that causes error to this bug report. Is an article from opensource.com.

My other PDF reader, Zathura, can show the PDF correctly.

I'm also attaching a similar PDF, also from opensource.com, but this one opens correctly with Papers.

I think this is the bug, already fixed, on upstream: https://gitlab.gnome.org/GNOME/Incubator/papers/-/issues/346. I tested with the Flatpak and it did work.

[Marcos Alano (mhalano)]

The strange part is: the patch for this problem is in place, so maybe is something different or similar.

[Marcos Alano (mhalano)]

I executed `strace /usr/bin/papers 5_open_source_collaboration_tools.pdf >papers.log 2>&1` and attached the result.

I would like to understand why it's using the llvmpipe if my NVIDIA GPU is, theoretically, working.

[Sudhakar Verma (sudhackar)]

Hello Marcos
Have you made contact with upstream on this yet?

[Marcos Alano (mhalano)]

Hi Sudhakar,

No, I don't. Should I? The Flatpak works, so I don't know for sure if I should.

[Marcos Alano (mhalano)]

Any news about that? The problem doesn't happen at all when I'm opening the file with the Flatpak version. I also can use xdg-open because of the path in $XDG_DATA_DIRS put my Flatpak install before /usr/share.
If I execute over command line with `papers filename` it also happens.
