Maybe related to bug 746737 ?

I'm using WebKitGtk+ with my own JHBuild setting:
https://github.com/tanty/jhbuild-epiphany/tree/master

Epiphany 3.20.1 and WebKit 2.12.1

I'm running Epiphany with the dconf key:

"process-model" = "shared-secondary-process"

The compilation was done with CMake args:

'-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g1 -DNDEBUG -DG_DISABLE_CAST_CHECKS"'

---

I clicked in a link leading to a PDF. Since I have compiled with support for the evince document viewer, the document was opened in another tab.

I presed Ctrl+s to save. The dialog popped up and I selected the location and pressed "Save".

Epiphany SIGSEVed at web_resource_get_data_cb. The PDF file is "saved" but has 0bytes.

Can be reproduced with MIDI files as well:

Can you post steps you follow for reproducing it?
Comment 3 Michael Catanzaro 2018-04-06 17:17:04 UTC 
Downloading it works fine here, in both Tech Preview and system Epiphany -p.
Comment 4 Kai Lüke 2018-04-06 20:43:27 UTC 
Clicking on it will play the file in the browser with GStreamer. Ctrl-S and pressing Save directly crashes for me on 3.28.0.1-1 Debian sid.
Comment 5 Michael Catanzaro 2018-04-06 20:51:43 UTC 
Can you post a backtrace please? We don't have the required codecs to play that file in our Flatpak runtime, nor in Fedora.
Comment 6 Kai Lüke 2018-04-08 16:11:37 UTC 
I thought it would be the same as linked but yes, that's maybe a bit outdated.
I can also reproduce it with OGG Vorbis:

OK, I can reproduce with that. And that last backtrace is superior to the others that were posted here: thanks.
