KMyMoney crashes when importing transactions via KBanking/AqBanking

If I try to import transactions using AqBanking, it downloads the transactions and then says it's
OK to click close to close the window. At that point, KMyMoney crashes -- every time. Here is the crash while being run from gdb, and the backtrace with debugging symbols installed:

KMyMoneyPlugin::KMMStatementInterface::import start

I have had this problem ever since upgrading to an earlier release of Ubuntu than this one -- maybe 16.10?

Requested info from guidelines:

1) ryanov@obelisk:~/src$ lsb_release -rd
Description: Ubuntu 17.04
Release: 17.04

2) ryanov@obelisk:~/src$ apt-cache policy kmymoney
kmymoney:
  Installed: 4.8.0-2
  Candidate: 4.8.0-2
  Version table:
 *** 4.8.0-2 500
        500 http://us.archive.ubuntu.com/ubuntu zesty/universe i386 Packages
        100 /var/lib/dpkg/status

3) My transactions should have been imported.

4) Segmentation fault instead.

Apport tells me my bug report isn't useful. I suspect this is a KDE/GNOME thing. The backtrace looks useful enough.
