Package: dia
Version: 0.97.3+git20160930-6
Severity: important
--- Please enter the report below this line. ---
The Python console works perfectly fine except when a user attempts to
invoke `help()` -- without arguments.
In this case Dia freezes, and there's no obvious way to revert it to the
normal state (so any unsaved work is essentially lost). The problem is
caused by the fact that `help()` is interactive: it starts its own
subshell and is waiting for user input (or ^D).
Non-interactive invocations such as `help("topics")` or
`help("keywords")` complete normally.
The backtrace (from gdb) is as follows:
