gnome-shell crashed with SIGABRT

[Rocko]

gnome-shell crashes with this bug every time that:

* I am editing a file in geany
* I open the Find window (CTRL-F) and it opens on another monitor
* I type in some un-findable text in the find window and press ENTER (or click the Next button)

The system beeps to indicate that the text isn't found, but then crashes.

Note especially that the find window must be on the other monitor - if it's on the same monitor as geany, gnome-shell doesn't crash.

(Note: I originally thought that if I moved the find window to the other window and then searched, gnome-shell crashed, but I think what happens is a) I open the window, b) I move it, search for something, and it works, c) I close it and re-open it - it then opens on the other monitor and searching will crash gnome-shell.)

gnome-shell restarts, but the crash causes data loss, as most of the running applications don't reappear when it restarts.

In case it's relevant, I have a laptop screen set at 2048x1152 and an external monitor configured to be above it at 2560x1440.

This was previously reported as bug #1849249, but that bug has been marked as fixed.
