Package: libqt5core5a
Version: 5.7.1~20161021+dfsg-6
Severity: important

Hello,

I get a Qt5 related segfault when exiting any of the application provided by the
`calibre` package. Please re-assign to correct package if appropriate.

In the syslog I see:

```
Nov 25 17:52:21 glossy kernel: [21774.794341] QDBusConnection[20621]: segfault at 7f3f543dd220 ip 00007f3fac31eb8f sp 00007f3f57ffcb90 error 4 in libQt5Core.so.5.7.1[7f3fac065000+4cd000]
```

Backtrace (could not find any useful `-dbgsym` packages to install):

```
