Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921,
reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
  Gnome Shell crashes with SIGSEGV when Android emulator started

Status in gjs package in Ubuntu:
  Incomplete
Status in gnome-shell package in Ubuntu:
  Incomplete

Bug description:
  I am filing this bug with gjs because the behaviour started after
  upgrading to 1.52.5-0ubuntu18.04.1

  Steps to reproduce are:

  1. Launch an Android emulator from Android Studio: I used all default
  settings and Andoid Pie x86 image

  2. Change workspace via hotkey

  3. Result is gnome-shell crashes and resets

  Workaround is to run:
  sudo apt install libgjs0g=1.52.1-1ubuntu1
  sudo apt install gjs=1.52.1-1ubuntu1

  This is from /var/log/syslog at the time of the gnome-shell crash
