Hello Everyone,
I am using gpsd and gpsmon version 3.20 (compiled from source) on my Raspberry PI 2, that's running Slackware-ARM current (Sarpi2).
Previously I was using gpsd version 3.17 on a Raspberry PI 1, on Slackware ARM 14.2, and there everything worked fine.
Now I moved my config and GPS device over to the RPi2 and for some reason gpsmon crashes soon after being started.
I tried to go back to gpsd-3.17, and other versions in between, but all of them seem to produce the crash.
GPSd itself seems to work fine. It detects my U-Blox GPS received, that's hooked to the serial port of the RPi2:

So as far as I could determine, everything works fine gpsd-wise, but when I start gpsmon, it always crashes, and this is all the output it produces:
