Public bug reported:
After upgrade to ubuntu 16.04 the problem appeared in calculator: if one
uses keyboard for expression input, the calculator window freezes
forever after asterisk ('*' — shift+8) is pressed. If the on-screen
multiplication sign is pressed instead, the problem doesn't occur.
I tried with my default locale (Russian) and with the English one
(LANG=C LC_ALL=en_US.utf8 LANGUAGE=en) as well, the problem remains in
both cases. The calculator mode (basic/advanced/etc) also doesn't change
the behavior.
If I interrupt the execution from the gdb at the moment of freeze, the
stacktrace is slightly different from run to run:
