(I got this crash without attempting to opt in into wayland.)

Annoyingly just after each new login. every day....

Only happens when I don't run startx as root (I know that it's not a good thing to do but was just checking things out.)

Ocure randomly (even without wayland used atall)

Crash when I try to paste (Ctrl+V) a bitmap from clipboard to a Pidgin message.

Occurred during Start-up of Gnome 3.16 (Ubuntu 15.04). I have not Wayland installed.

Additional note: This bug occurs frequently, about once or twice everyday.

Same for gome 3.18

It would be great, if a developer could have a look at this bug. It currently affects 55 people, bug heat 246 and - on my system - there are crashes of gjs everyday. Also, please not that this bug has nothing to do with Wayland. It also affects X11 users. Thanks a lot!

I'm not sure, but I think this but might be related: https://bugs.launchpad.net/ubuntu-gnome/+bug/1432068

That is likely gnome-documents search provider crashing

What does "Status incomplete" mean? Do you need any additional info?

Hi GT,

The status "incomplete" is for the upstream project gjs. The status for Ubuntu GNOME however is confirmed. The crash seems to occur when searching for an application via activities but we are currently trying to reproduce this reliably in order to provide the relevant information upstream if necessary.

Thanks

Steps to reproduce:

- in one terminal run /usr/bin/gnome-documents --gapplication-service
- in another terminal run dbus-send --print-reply --dest=org.gnome.Documents /org/gnome/Documents/SearchProvider org.gnome.Shell.SearchProvider2.GetInitialResultSet array:string:"search"

Note: you must run dbus-send within 10 seconds of the 1st command, because gnome-documents exits when it's idle.

Note: you can use DOCUMENTS_RUN_DEBUG=yes gnome-documents --gapplication-service in step 1 to get the crash under gdb

I ran the reproduction scenarion under valgrind and saw this:
