Hi, everybody, I'm not sure it is modemmanager's fault here, but as soon as I try to insert an infrared (pretty standard) dongle I see in dmesg that modemmanager crashes with a segfault. Ubuntu (Mate) 16.04 on x86-64, modemmanager version 1.4.12-1ubuntu1 installed The dongle is: [lsusb] Bus 001 Device 006: ID 066f:4200 SigmaTel, Inc. STIr4200 IrDA Bridge and when inserting it I see [dmesg] [ 795.674472] usb 1-1.2: new full-speed USB device number 6 using ehci-pci [ 795.767970] usb 1-1.2: New USB device found, idVendor=066f, idProduct=4200 [ 795.767978] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 795.767981] usb 1-1.2: Product: IrDA/USB Bridge [ 795.767984] usb 1-1.2: Manufacturer: Sigmatel Inc [ 795.768844] SigmaTel STIr4200 IRDA/USB found at address 6, Vendor: 66f, Product: 4200 [ 795.769263] stir4200 1-1.2:1.0: IrDA: Registered SigmaTel device irda0 [ 795.809763] ModemManager[3105]: segfault at 0 ip 0000000000431ab3 sp 00007ffd4c29bf40 error 4 in ModemManager[400000+103000] (this happens on a Dell Latitude E6330, in case it is relevant) Thank you for your attention, Steo
Any chance you can get debug logs and a backtrace when reproducing it? https://www.freedesktop.org/wiki/Software/ModemManager/Debugging/ For the backtrace, just: $ gdb --args /usr/sbin/ModemManager --debug Then type "r" (run), and when it crashes, type "b" (backtrace)
