Package: vlc
Version: 2.2.1-2+b1
Severity: important

Hi,

when I start vlc and then undock my laptop, vlc crashes. This is from
dmesg:

[  371.966646] usb 3-1.1.3.2: USB disconnect, device number 9
[  371.970358] vlc[3908]: segfault at 28 ip 00007fef7cb2a4c7 sp
00007fef7c1ef210 error 4 in libQt5Widgets.so.5.4.2[7fef7c991000+66e000]
[  372.402515] thinkpad_acpi: undocked from hotplug port replicator

The system is a X220 Lenove Thinkpad with a docking station and external
monitor.

I suspect it was a combination of bugs, many bugs usually associated to Qt 
where fixed with the latest Plasma uploads for example (or maybe workarounds 
implemented).
