Crashes on a number of gestures when panels are set to auto-hide

[richardshiue]

Running Manjaro/KDE over here. Touchegg v2.0.2

Only affects a small fraction of users, so not a big deal

If a session is started with panels(or taskbars) set to "auto-hide", gestures that provoke the change desktop and minimize/maximize actions (maybe others as well, but I haven't tested) result in a segmentation fault (core dumped) crash. Changing the panel settings to "always visible" seems to fix the issue for the rest of the session, even if the change is reverted afterwards and touchegg is restarted.

I suspect that X11::getDesktopWorkarea() is having a hard time figuring out the info it needs, from running it using gdb.

Sorry if I messed anything up. This is my first ever issue submit on any repository. Though, thanks for all the work that went into this project!

Same thing here with latte-dock on opensuse tumbleweed
