Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate a useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system

Is there any chance that you remember what you did? Possible would be workspaceview, windowoverview and workspace switching.

Workspace switching - I seem to remember that I clicked on a program in the
dock that was running on another workspace and gala crashed during the
switch. This has happened before on numerous occasions.

rev324 should fix a number of those crashes. Please reopen if we still haven't got all of them.

This is still occurring - not fixed by rev324.

Using firefox and started a program under latest Wine.

Using Firefox, Qbittorrent, and Pantheon Files. Flash was turned on on Firefox. Using FlashOnOff on it. Using ALT+TAB to alternate between apps. No multiple monitors.

I had this crash when I tried to alt-tab from a fullscreen minecraft to a terminal window.

From a duplicate:

"This happened while having open Chromium and JDownloader, and Alt-Tab switching between them."

Needs a new report from Isis

@codygarver: Is there anyway to reproduce this bug? Like when/how could this bug occur?

[Expired for Gala because there has been no activity for 60 days.]

Also gala crashed when Alt+Tab in freya beta 1.
