Maybe related to 13299, but without window wasn't maximized. To reproduce start mousepad, make a new tab with ctrl-n and drag it outside the main window. On my machine this first freezes mousepad and shortly after the program disappears. I'm running Xubuntu 16.04.1 inside a virtual box.
I can reproduce this, it doesn't seem to be a crash in Mousepad though.

Reliably reproducible here. Xubuntu 16.10 amd64.
I can't reproduce, I open mousepad(0.4.0, gtk2 from distro repository), create a new tab(ctrl+n) and drag it to desktop, it just opens another window with that document. Arch Linux here mostly updated last week.
Not reproducible for me. Using Debian testing (stretch) and mousepad version 0.4.0. After creating a new tab with ctrl+n and draging that tab to the desktop it opens another window. Same as comment above.
Just confirming the same. Unexpected quit upon dragging a tab into desktop. Don't know if it makes any difference, but have 4 desktops and Mousepad was open on one only. Running Ubuntu (Studio) 16.04.2 / Xfce 4.12
Found the bug after some sleuthing, fixed in: https://git.xfce.org/apps/mousepad/commit/?id=e3718b23026117ef653a539f504c13d6a672fd7f GTK+ upstream bug: https://bugzilla.gnome.org/show_bug.cgi?id=744385 Where I found a workaround: https://github.com/f2404/xfce4-terminal3/commit/06eace541aa4bd93d7e5204a856467cdf76de104 Others affected/related: https://bugs.launchpad.net/midori/+bug/1492041 https://github.com/mypaint/mypaint/issues/194 There are still versions of GTK3 between around 3.10 and 3.16 which will still crash, suggestions on better fix welcome.
