[Bug 1576424] [NEW] Gimp crashes with text tool & caps lock

Gimp crashes with a segfault when I use caps lock while renaming a
layer. Steps to reproduce:

1. Open a new blank gimp document
2. select the text tool
3. type a couple of words of text (gimp will create a text layer above the background layer)
4. with the text tool still selected, click on the background layer (just to move away from the text layer)
5. now double click on the text layer to rename the layer (layer name gets highlighted)
6. press the caps lock key
7. click on the background layer again (without renaming or doing anything to the text layer)
Now repeat steps 5 and 6.
Gimp crashes.

I can force this to happen every time I launch Gimp. Rebooting makes no
difference. It seems to be the second time I press caps lock that forces
the crash. I tried launching Gimp with caps lock on vs caps lock off,
but I don't believe it made any difference. I can force a crash every
time following the above sequence.

I deleted my gimp preferences folder then rebooted for good measure.
Gimp created a fresh preferences folder, but it hasn't solved the
problem. I was originally in single window mode, but the new preferences
folder put me back to multi window, but it crashes either way.

I ran dmesg | tail after the crash and got the following line:

gimp-2.8[2976]: segfault at 14 ip 00007ff5100e0cd9 sp 00007ffef11bfcb0
error 4 in libgtk-x11-2.0.so.0.2400.30[7ff51001b000+43e000]

I'm using a fresh install of Xubuntu 16.04 with nvidia 361.42 driver
(available from the Additional Drivers tab). In that same tab, I also
have enabled Processor microcode firmware for Intel CPUs. Terminal tells
me Gimp version is 2.8.16-1ubuntu1

I'm not very experienced with bug reporting and not sure what other
information I need to supply. Gimp was absolutely rock solid on this
machine with 15.10, so it may be a Xubuntu issue.

Hope someone can take a look at this. Thanks.
