In my opinion crash happens because of direct call of perl exit() in GTK
signal handlers.
To reproduce bug: start tinyca2 without arguments, press cancel in
create CA dialog, then select exit in main menu.
Here is stack trace from crash:

Looks like bug is only reproducible with some specific libraries
version. It can be reproduced in Ubuntu 16.04.3 with following packages
versions:
ii libglib2.0-0:amd64 2.48.2-0ubuntu1
ii libgtk2-perl 2:1.2498-1
ii libgtk2.0-0:amd64 2.24.30-1ubuntu1.16.0
ii tinyca 0.7.5-6
The same tinyca version does not crash in debian 9.3 with following
packages versions:
ii libglib2.0-0:amd64 2.50.3-2
ii libgtk2-perl 2:1.2499-1
ii libgtk2.0-0:amd64 2.24.31-2
ii tinyca 0.7.5-6
I've created simple patch for Ubuntu, but not sure if it is necessary in future
versions.
