Hi, i'm using qlcplus from a lot of time with qt4
today i have bought a new pc, i have installed Opensuse Leap 15.0 with qt5 and i have compiled qlcplus from git

Initially my user wasn't in dialout group and all FTDI-USB interfaces was identified with a lot of strange characters....
Now i'm in dialout group, and first FTDI-USB interface is still identified with strange characters, but the others are correctly identified.

I have a peperoni rodin 1 interface too and i can use it as an input interface and as an output one.
If i'm using it as output, when i leave checkbox for free it i have a segmentation fault (core dumped)

After that, when i restart qlcplus sometime all FTDI-USB interfaces are correctly identified, sometime not.

where i can find core dump so to attach it here?

same crash happen on USBDMX2.1

i think it may be the disctructor that don't call removeFromMap()

another think noticed is:
- if before uncheck peperoni_device_output_checkbox i check peperoni_device_input_checkbox on same interface, qlc don't crash
