DetailsDescription:
lircd segfaults if I disconnect an USB-disk. Additional info: I have an USB IR-reciever, driven with atilibusb. * package versions lirc-utils 0.9.1.a-7 libusb 1.0.19-1 * config and/or log files etc. core-dump included Steps to reproduce: 1. start lircd through systemctl: sudo systemctl start lircd 2. start irexec (from user): irexec -d 3. connect the USB-hard-drive (it will automounts through udiskie+udisks2) 4. unmount the drive 5. plug out the drive. |
